Resolution Note (fix version 2021.1):
Fixed in 2021.1.0a7
Temporary work around until this is fixed properly:
Etiher enable 'Update When Offscreen' or disable shadows on the SkinnedMeshRenderers. This will stop the assertion from failing But will cost performance or stop shadows from rendering respectively.
