@spiral bison uploaded a log, I've been using Axiom with the same mods for months. It worked one night roughly a week ago, then the next morning, my instance wouldn't even open. Axiom is mentioned a few times in the red on the crash report, so I disabled it and my game runs fine. However, that is not what I want to do.
Crash Report:
- Fabric 0.15.7 on 1.20.4
Possible Solutions:
- Update Fabric from 0.15.7 to 0.15.10
