I have encountered some issues while runing python -m igibson.examples.environments.env_nonint_example, I received the following error message:

I also met this problem.
And I've tried check the egl and downgrading the nvidia driver from 525 to 470.
Make no sense. I still can not launch the demo.

I tackled this issue by reinstall the ubuntu system, while I compare the links between the error enviroment and the executable enviroment by run ldconfig -p | grep EGL, and here is the difference:
