Describe the bug
AutoHud crashing because one mod, Im not sure if ImmediatelyFast or other mod is the cause but I posted a log.

ModVersion: AutoHUD 1.20.1 6.1 (Forge)

I remember ImmediatelyFast causing issues before. Try disabling the HUD batching feature.

For me its crashing because of Yet Another Config Lib mod. so check if that is maybe the cause rather than ImmediatelyFast because ImmediatelyFast works fine with AutoHud for me. And if Yet Another Config Lib was the problem all along, then you can just close this issue because an update to Yet Another Config Lib is already out which fixes the crash.

Edit: i actually just found out that AutoHud and KronHud causes a crash, so i guess you can try to check that as well.

I cannot reproduce the crash, so I believe it to be YACL. Annoyingly, it still hasn't gotten an update to fix it from running on 1.20.1 :/ without YACL, everything seems to be working fine
