Minecraft continues to be one of the world’s most played games, but even this blocky juggernaut can run into technical problems. Whether you’re using Java Edition or Bedrock Edition (across Windows 10/11, Xbox, PlayStation, Switch, or mobile), this guide covers all the most common issues—and how to fix them fast.

This article is updated for 2025 and includes the newest launcher changes, Microsoft account updates, and platform-specific fixes.

1. Minecraft Won’t Launch

Applies to: Java Edition, Bedrock Edition (PC and mobile)

Symptoms:

• Nothing happens when clicking "Play"

• Game freezes on the Mojang or Xbox splash screen

• Error codes like "Exit Code: 1", "GLFW error", or "Unable to locate Java runtime"

Causes:

• Corrupted installation

• Missing or outdated Java (Java Edition)

• Conflicting graphics drivers

• Launcher errors or cached data issues

Fixes:

For Java Edition (Windows, macOS):

• Update Java manually: Download and install the latest version from java.com.

• Check your GPU drivers: Go to your GPU manufacturer’s website (NVIDIA, AMD, Intel) and update to the latest version.

• Use the official launcher only: Third-party launchers may not handle updates properly.

• Run as Administrator: Right-click the Minecraft Launcher and choose "Run as administrator."

• Delete launcher cache: Go to %AppData%/.minecraft and back up your saves, then delete launcher_profiles.json.

For Bedrock Edition (Windows 10/11):

• Repair from Windows settings: Navigate to Settings > Apps > Minecraft > Advanced Options > Repair.

• Reset the app if repair doesn’t work.

• Reinstall Minecraft using the Microsoft Store or Xbox app.

2. Minecraft Keeps Crashing

Applies to: Java Edition and Bedrock Edition (all devices)

Symptoms:

• Game loads but suddenly closes

• Freezing after entering a world

• Memory-related errors or OpenGL crashes

Causes:

• Mod or shader incompatibility

• Low system resources

• Corrupted game files or saved worlds

• Outdated graphics or system drivers

Fixes:

Java Edition:

• Remove mods or resource packs: Temporarily delete or move everything from the .minecraft/mods and .minecraft/resourcepacks folders.

• Check allocated RAM: Use the launcher to allocate 2–4 GB of RAM via JVM arguments (e.g., -Xmx4G).

• Disable VBOs and Fancy Graphics: Turn off advanced video settings in-game or via options.txt.

• Check crash reports: Located in .minecraft/crash-reports, these files often indicate the cause.

Bedrock Edition:

• Disable custom packs: Third-party textures and add-ons are a common cause of crashes.

• Make sure your device meets system requirements: On Android or iOS, Minecraft may crash on older phones with limited RAM.

• Reinstall the app if nothing else works, and ensure you're signed in to the correct Microsoft or Xbox account.

3. Multiplayer Not Working

Applies to: Java Edition, Bedrock Edition (console, mobile, PC)

Symptoms:

• "Unable to connect to world"

• "Connection timed out"

• "Outdated client" or authentication errors

• Server list not loading

Causes:

• Poor internet connection or firewall settings

• NAT type issues on consoles

• Version mismatch between players

• Xbox Live or PSN account not configured properly

Fixes:

Java Edition:

• Use the same game version: Servers are version-specific. Change your game version in the Minecraft Launcher under “Installations.”

• Check server status: Make sure the server is online and not under maintenance.

• Allow Minecraft through firewall: On Windows, go to Firewall settings and allow both Minecraft and the Java(TM) Platform SE Binary.

• Flush your DNS: Run ipconfig /flushdns in Command Prompt (Windows) to reset your network cache.

Bedrock Edition (Console & Mobile):

• Ensure Xbox Live or PlayStation Plus is active: These are required for online play.

• Check your NAT type: A strict NAT can block multiplayer. Set your router to use UPnP or port forward Xbox Live services.

• Log out and back into Microsoft/Xbox account.

• Reboot your network hardware: Fully power off and restart your router/modem.

4. Minecraft is Lagging or Running Slowly

Applies to: Java and Bedrock Editions

Symptoms:

• Choppy frame rate

• Freezing during exploration or combat

• Long world load times

• Lag spikes in multiplayer

Causes:

• High render distance or fancy graphics

• Insufficient RAM or CPU

• Large or corrupted world files

• Poor Wi-Fi signal (multiplayer)

Fixes:

Java Edition (PC):

• Install OptiFine: This optimization mod allows you to tweak performance settings like chunk loading, animations, and VSync.

• Lower in-game video settings: Set Render Distance to 8 chunks or less, disable Smooth Lighting and Particles.

• Close background apps: Chrome, Discord, OBS, and others consume RAM and CPU.

• Use dedicated GPU: On laptops, force Minecraft to run on the high-performance GPU through your graphics control panel.

Bedrock Edition (Console/Mobile):

• Reduce render distance in Settings > Video.

• Use wired internet if possible, especially for Realms and servers.

• Restart your device regularly to free up system memory.

5. Audio Not Working

Applies to: All Minecraft editions and platforms

Symptoms:

• No game sounds or music

• Only some sounds work (e.g., UI but no environmental noise)

• Sound works in other apps but not Minecraft

Causes:

• Minecraft muted in system audio mixer

• Wrong audio output selected

• Conflicts with sound drivers or audio devices

Fixes:

• Check system volume mixer: On Windows, right-click the speaker icon and make sure Minecraft isn't muted.

• Select the correct output device: In-game under Settings > Audio (Bedrock) or via your system settings (Java).

• Reinstall or update sound drivers.

• Unplug and replug audio devices, especially USB headsets.

• Force resource reload: In Java Edition, press F3 + T to reload all assets, including audio files.

6. World Won’t Load or Gets Stuck on “Building Terrain”

Applies to: Primarily Bedrock Edition (mobile, console), but can happen on Java

Symptoms:

• Game hangs while loading a world or Realm

• “Generating World” or “Building Terrain” screen never completes

• World crashes after loading

Causes:

• Corrupted world files

• Device memory limits reached

• Incompatible add-ons or texture packs

Fixes:

• Try creating a new world: If it works, the old one may be corrupt.

• Move or delete saved world files: Back them up and remove them from local storage.

• Clear Minecraft cache:

  • On Android: Clear cache via App Info > Storage.

  • On Xbox: Go to Settings > Storage > Clear local saved games.

• Reinstall the game if multiple worlds won’t load, and ensure cloud save sync is active.

7. Login and Account Issues

Applies to: Java Edition (via Microsoft accounts), Bedrock Edition (Xbox, PlayStation, Nintendo)

Symptoms:

• "Invalid credentials" or login loop

• Can’t sign into Microsoft or Xbox Live

• Launcher fails to recognize account

Causes:

• Wrong Microsoft account used

• Two-factor authentication not set up properly

• Minecraft license not linked to your Microsoft account

Fixes:

• Reset Microsoft password and try logging in via account.microsoft.com.

• Check account migration status if you came from Mojang accounts.

• Reinstall launcher and sign in again.
