I'm playing 1.20.1 and I keep receiving this crash msg when I try and load up the game. I've tried both versions of the PSWG mod for 1.20.1 and installed the most recent version of fabric 1.20.1 along with fabric API. I have tried this mod separate from all of my other current mods and I am sure it's an issue with PSWG or something I'm doing wrong.
The game crashed whilst initializing game
Error: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'pswg'!

This is the crash report

Can you post your entire crash log? I don't think this is the most recent version of Fabric API.

This is an issue with that particular version of Fabric Loader. I recommend you update to 1.20.2 with the latest version of everything, or else use Fabric Loader 0.14.22
