webots: The process crashed some time after starting successfully

Describe the Bug After trying to go through the tutorial for creating the controller here I get a warning:

WARNING: e_p: The process crashed some time after starting successfully.
WARNING: 'e_p' controller crashed.

Steps to Reproduce Follow the tutorial for creating a new controller and use the same code in C++ or Python. The bug seems to happen when creating a Robot object.

In the mean time I upgraded to macOS 12.3.1, and it’s still crashing for me with Python 3.9 (from python.org):
