Minecraft world showing in launcher but not in the game and files.

There is a bug with the Xbox app updating Minecraft inadvertently deletes the worlds on the game. So that is why the message shows on the launcher. It shouldn't affect you, as you are using a mac.

Hi, Jacob! I'm sorry to hear you're having trouble with your Minecraft world not showing in the game on your PC. No worries, I'm happy to assist you with this today.

Please try to follow these steps. Make sure to close any games and applications before proceeding.

Ensure that you are on the most recent version of the Xbox app and the Game

Microsoft Store app > Downloads > Get updates/Update all

Ensure that you have updated your PC to the most recent version of Windows, including optional updates

PC Settings > Windows Update > Check for updates > Install

Open the Xbox app on PC > (the game) >Manage > Files > Verify and Repair

Sign Out of Your Accounts (Xbox App and Microsoft Store App):

Open the Microsoft Store by pressing Windows Key + S, typing Microsoft Store, and selecting App Settings.

Click on Repair and then Reset the app.

Repeat the same process for the Xbox App and Minecraft launcher

Restart Your Device:

After repairing and resetting both apps, restart your device.

Sign back into both the Xbox App and the Microsoft Store using the same email.

Please let me know if that works. Thank you!

You can check it under Settings > General > Minecraft: Java Edition Settings > Show historical versions of Minecraft: Java Edition in the Launcher. You can also try deleting your Minecraft files, look for “.minecraft” file located in the AppData folder. Type “%appdata%” in the Windows search bar. then delete the “.minecraft” file completely from the folder that opens. After this step, by opening the Microsoft Store, you can try to download the Minecraft Launcher application and launch the game.

If it persists, I suggest you check with Minecraft team so their technical team can further check this error code. You can submit the request using the link below:

Hello, My name is Jesse. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

Hit the windows key + R and type %appdata% and then proceed to find the .minecraft folder and delete it and then open up the launcher again and it will take you to the login screen. Your worlds are gone but you can drag your world files out and put it on your desktop until after running Minecraft again so it creates the folder necessary to put your worlds back sorry for the aneurysm you gained from reading that. (take the world files out first before deleting the .minecraft folder)

Close your launcher. Navigate to your .minecraft folder and delete the launcher_msa_credentials.bin file. Then, run the launcher and log back in.
