Steps to reproduce:
1. Open the attached project "ReducedRepro.zip"
2. Click on "PandaCupScene_v02" and observe the "Rig" tab
3. Animation Type should be set to "Legacy"
4. Enter play mode and crash

Expected: The animation shouldn't crash the editor
Actual: If the animation type is set to Legacy, Unity crashes on

"0x000000014178D658 (Unity) AnimationBinder::BindCurves
0x0000000141793C9D (Unity) Animation::RebuildStateForEverything
0x0000000141794AA0 (Unity) Animation::SampleInternal
0x0000000141795B01 (Unity) Animation::UpdateAnimation
0x000000014179519D (Unity) Animation::SetVisibleInternal"

Note: The asset preview on the bottom right has to be visible for the crash to happen, meaning you should have "PandaCupScene_v02" still selected when entering play mode
