Update to 1.21.3
Right now, it's able to launch up on 1.21.3 but crashes as soon as I click into the resources

Same problem here, I can open the resource pack sub-menu, as soon as I hover over a folder, it crashes

Same, I create a folder and immediately the game crashes.

Send your game logs, 1.21.3 work for me perfectly

How could I fix the problem with the logs? Do you have any ideas?

If you share the game logs here, then we will be able to see the reason for your error

Thanks for the offer, but somehow it's working now, maybe I missed some dependencies.
