Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.79
Broken: version: 3.0.0 Release Candidate, branch: master, commit date: 2021-11-30 10:50, hash: rB4b971bb87c03
Worked: 2.93.0 - 2.93.7
Short description of error
Blender 3.0 cannot import some Mixamo animations. But Blender 2.93 does it right.
Apparently the issue is related to the amount of UV maps.
Exact steps for others to reproduce the error
Just try to import the fbx I attached (excuse me for the file size)
