My Unity Version is 2020.3.15f2 Personal.
Before doing all of the staff I have imported Starter asset and animation rigging and then I have checked animation rigging was working perfectly on starter asset in built character.
Now I have imported multiple assets as well as a maximo character Ch5.Now unfortunately animation rigging is not working i.e. No movement either multi aim constraint or two bone ik. I have been tried by changing humanoid to Generic but continuously showing the bellow error and no movement by target in Game view .
InvalidOperationException: The TransformStreamHandle cannot be resolved.

I will appreciate any kind suggestions or help .
