Using v2021.3.20f1 I used the "Third Person" template.
I downloaded the "Standing to Crouched" on Heraklios By A. Dizon animation on Mixamo: https://www.mixamo.com/#/?page=1&query=standing+to+crouch with:
- Format "FBX for Unity(.fbx)"
- "Without Skin"
- 60fps
- None for keyframe reduction.
I saved it in "Assets/Character/Animations/Standing To Crouched"
I then opened it up in the Inspector > Rig, and changed the "Animation Type" to "Humanoid".

File 'Standing To Crouched' copied Avatar Rig Configuration mis-match. Transform hierarchy does not match:
Transform 'Hips' for human bone 'Hips' not found
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
Note that if I then use a character model downloaded from Mixamo this "Hips" errors goes away, but the issue with the animation remains:
