actually, just delete this file and it will work:

/home/user/.minecraft/webcache2/Default/Preferences

I had to write a shell script to autodelete that file everytime i close minecraft. I hope this gets fixed quickly.

I am using a Steam Deck with Arch6.13.4-arch1-1

@alchemy you can edit the application launch properties to

Program: rm

Command-Line Arguments: ~/.minecraft/webcache2/Default/Preferences '|' minecraft-launcher

Just got the exact same issue yesterday and found the exact same solution(btw, also Arch user)

rm $HOME/.minecraft/webcache2/Default/Preferences

but it’s quite annoying, hope that can got fixed soon

P.S. I got some different logs every time I click “Try Again”, may be useful

[Error: 2025-03-06 13:38:58.862750360: nWq20LX9f84=: app.0ce5389a.bundle.js(2)] OnConsoleMessage: TypeError: Cannot read properties of undefined (reading 'id')

I’m on Ubuntu 24.04 and this is still happening.

The workaround worked for me too.
