I took another look and there was more info in the error logs:

Loading the physx bundle (you have to check autoload and then restart the code app) loads the physx vehicle extension without errors.

4

Yes correct loading the bundle is the best way to ensure you have all the pieces. Also the USD schemas that are required for the physics need application restart.
We have internally a bug report to make this more clear to the user and not even allow omni.physx extensions to be loadable if the restart is required.
Sorry for the inconvenience.
