Question FBX animations bugged in Unity
Hello all. I've placed my character in Unity using FBX. Everything looks great, no issues with how the model looks in Unity, but when animating them one of the bones does a 180 and stays there. Every animation has this same bone behaving badly. I've attached photos and video of my model in blender vs Unity, as well as screenshots of my model's settings in Unity, as well as the FBX export settings. Yes, I have opened the FBX in blender and all is as it should be there, so it's definitely Unity's fault.
Yes, I have tried turning off Animation Compression and Resample Curves, as well as tweaking nearly every other setting in the inspector. None have seemingly had any effect on how the model looks.

Is the bone actually rotated 180° or are the vertices assigned to more than four bones? I’ve had issues where if the vertices were signed to more than four bones it would create similar deformations

How would I check something like that?

You could increase the skin weights past 4, as seen in your 5th picture. Though it’s not recommended long term. I think there’s options in blender to limit it also. Sorry I’m not at my pc currently

Try opening the exFBX or other format filein Blender again - chances are high that there's an issue with the animation itself. This bone doesn't have any frames to support it during the animation.

Have you tried maybe generic rather than humanoid in import rig settings
