Animations not working when building for iOS (But they work in Unity Editor)

Hi! So I’ve been encountering the very strange occurrence of any animations not working in iOS.

I sadly have no idea what might cause this, but the issue occurs for every Unity Version I’ve tried (2021.1.0b2, 2020.2.1f1). I’ve tried on both iPad and iOS (both on 14.3). I also tried setting the quality on mobile to a higher setting, which also didn’t help. It doesn’t matter what the animation is doing, none work. I use Xcode 12.3 to compile.

The strange thing: When doing the same thing in 2018.3.0f2, it works perfectly fine.

If it helps, here is the animator:

Does anyone have any idea what might cause this?

Anyone? I also tried disabling code stripping, but that didn’t help.

Have you tried some other il2cpp platform? Such as Standalone set to use il2cpp scripting backend?
