can you confirm that in your nucleus folder the version file says version-2020.2.2.1106.md
if you see version-2020.2.1026.md that means you have the assets from the 2020.2 release and not the newer 2020.2.2 hotfix release
The issue is an update to the joint names for jetbot between 2020.2 and 2020.2.2
