Minecraft: Java Edition. Ultimate troubleshooting guide

Last updated on February 12, 2022

The steps on this page should help fix quite a few problems with Minecraft: Java Edition. Including:

  • Problems seeing skins
  • Loading issues
  • Exit codes 0, -1, etc.
  • Some FPS issues.

Try each of the steps in order, moving on to the next step if it doesn’t fix your issue.

Restart your PC

Restarting your PC should be your first troubleshooting step for most computer issues. It helps your PC run at it’s best, as well as clearing unnecessary temporary files.

Clear Compatibility Settings.

There’s a number of guides out there that ask you to try running Minecraft as Windows 7 or Vista. While these methods appear to work, they don’t fix the issue. They just work round it. For best results: clear your compatibility settings before trying the rest of the steps.

Right click the Minecraft launcher icon , click properties, and uncheck Run this program in compatibility mode

Note: this is only relevant for Windows devices.

Reset the Minecraft Launcher.

Occasionally corrupt launcher files can be the cause of the issues. Therefore, resetting the launcher is recommended. By-far the easiest method is to uninstall the launcher and reinstall it.

Your saves shouldn’t be affected by uninstalling the Launcher, but we recommend backing them up before hand, just in case.

If you’re on windows, and still use the old launcher (not the one from the Microsoft store) there’s an alternate method:

  • Browse to the launchers install folder:C:\Program Files (x86)\Minecraft
  • Delete everything in the install folder except MinecraftLauncher.exe
  • Restart Minecraft. The launcher will download fresh copies of all relevant files.

Use the old Launcher

Note: This step won’t work if you play Minecraft through Gamepass.

The new Minecraft Launcher from the Microsoft store has quite a few bugs currently. It’s often best to revert back to the old launcher until the new one’s fixed. Follow the steps below to get the old launcher installed.

  • Uninstall the launcher from the Microsoft store.
  • Open and click Download for Windows 7/8 to download the launcher.
    • Despite it’s name, the Windows 7/8 launcher still works on Windows 10 and 11.
  • Run the install file.

Recreate your .minecraft folder.

A lot of Minecraft issues can be resolved by recreating the .minecraft folder. The guide below expands in-page to guide you through the process.

Check your PC for incompatible programs.

Another common cause of Minecraft issues is having incompatible software installed on your computer.

Check your PC for any programs on this list, and take any action recommended on that page. The most common incompatible programs are:

  • Antivirus
    • Uninstall the antivirus to resolve.
  • GeForce Experience.
    • Disable the overlay to resolve.
  • Discord
    • Disable the overlay to resolve.

Check and clean your hosts file

The hosts file can be used to redirect your Minecraft traffic away from official servers. Follow this guide to check it.

Remember to change your password, if you had to clean your hosts file.

Run an adware scan.

Occasionally, adware can cause problems with Minecraft: Java edition.

Thankfully, the fix is pretty simple:

  • Check your installed programs for “Premier Opinion” and/or “Relevant Knowledge” and remove them if they’re installed.
  • Run an adware scan with AdwCleaner.

Check your PC username/file path for special characters.

Having special characters (!,@,#,é,ã,ø, etc.) in your PC’s username or file path can prevent Minecraft from running.

Remove any special characters and relaunch Minecraft. If the characters are in your username, you’ll need to make a new account on your PC.

Run CHKDSK to check and repair corrupt files.

Corrupt files on your PC can occasionally cause issues with Minecraft. To scan your PC for these files, and automatically repair them, follow this guide to run CHKDSK.

Note: this is only relevant for Windows devices.
