Segmentation fault of SapienRenderer

[yzzmxyx]

System:

• OS version: Ubuntu 20.04.6 LTS
• Python version (if applicable): Python 3.11
• SAPIEN version (pip freeze | grep sapien): 2.2.2
• Environment: Server with xvfb(uv virtual environment)

Describe the bug
I met this error in ManiSkill. When I run the following code, a "Segmentation fault (core dumped)" error occurs.

sapien.SapienRenderer.set_log_level("info")
self._renderer = sapien.SapienRenderer(**renderer_kwargs)

Screenshot:
Here is the screenshot of the error:

The same code can run in another Python 3.10 conda environment, so I think the problem may not lie in server hardware. Could you please tell me what the possible causes might be?

First, can you check that the segfault happens during initialization and not during shutdown (which would be just a bit annoying but will not affect your actual work). It was a known issue in SAPIEN 2. If it does happen during initialization, it would be quite hard to find the reason now since both SAPIEN 2 and Ubuntu 20.04 are a bit too old to debug, and upgrading your system and SAPIEN may be the best first step.
