I was made my first player model and wanted use it.... but first times I got crash everytime when I enter Inventory or go 3rd person...

The error I getting was:

java.lang.IllegalArgumentException: Cannot animate right_arm, which does not exist in model

I loaded my model in different Instance of Prism with only CPM loaded and Model was loading fine... and I started check the problematic mod via manual disabling and yep results was a one library mod named Bagus Lib is causing it due when its been enabled game crashes with that error...

here is the crash report : https://mclo.gs/5X05Owc

Game Version : 1.21.8
Loader : Neoforge

Note : is this should be reported to mod author ? Idk what am i do due that mod prob. needed from another mod

[Update] : yeah I can confirm its was causing crash ... currently only Bagus lib and mods needs it are disabled and everything of CPM works as intended...
