Short description of error
Whenever I try to extrude anything, blender crashes with a segfault. I was just about to create a minimalistic file only to find out, that it does not matter. In Object edit mode anytime I press E to extrude, blender segfaults. Also tried starting blender with factory settings and just trying to extrude the sample cube that is displayed by default behind the splash screen.
Since this is such a blocker, I assume the cause will have something to do with my setup.
Exact steps for others to reproduce the error
Expected result: the selected face is extruded.
Actual result: blender crashes with a segfault.

Some Linux distribution incorrectly compiled Blender with Python 3.9. The official Blender build of 2.83.5 doesn't use Python 3.9, because it's not compatible due to the use of
PyEval_ReleaseLock(). Please use the official version from our release page .Note the current version of Blender is 2.91 and the most recent corrective release of 2.83 LTS is 2.83.9.
