Found a bug in v4-1.1 (Fabric) (1.19.4)
If you move around anything in the resource pack menu and click done, when the loading bar reaches the end the screen doesn't fade out and let you back into the game like normal, it just hangs there and forces you to Alt+F4 to get out.

Here's my log file if that helps:

Ok, I found the issue. Thanks for reporting. I'll release a patch soon.
