@woeful dragon uploaded a log, Title says it all. From my limited fabric modding knowlage i think its probably a compatibility issue since it mentions mixins a lot but thats all i can tell from the log
- OpenJDK 64-Bit Server VM, version 21.0.2
- Fabric 0.15.11 on 1.20.6
Recommendations: - Unless you know what you're doing, modifying your JVM args could have unintended side effects. It's best to use the defaults.
- Update Dynamic Fps from 3.4.3 to 3.5.1
- Update Fabric API from 0.100.2+1.20.6 to 0.100.4
