Error retargeting Mixamo animations to ALS V4 Community

The Animations all work perfectly in the IK Retargeter but when retargeting any animation it crashes with this error: Assertion failed: OutPose.IsNormalized

I’m using UE 5.0.1

I have the same problem. In the new project, where there is nothing but metahuman, everything works fine. And it doesn’t work with decorations in the project.
Assertion failed: OutPose.IsNormalized() [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\Animation\AnimSequence.cpp] [Line: 1461]

I am trying to solve this problem for the second day. Try straightening the metahuman’s fingers. After that, retargeter began to work stably.

Jobatsu on YouTube helped me fix it, here is what they said:

  1. Make sure Metacarpal chains are set to none.
  2. Reset pose in IKRig and IKRetargeter
  3. Avoid posing fingers.
