System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2070 with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.63

Blender Version
Broken: version: 2.93.0, branch: master, commit date: 2021-06-02 11:21, hash: 84da05a8b8
Worked: (newest version of Blender that worked as expected)

Short description of error
Calling bpy.utils.register_class on a node socket class that is already registered by Blender crashes the software (NodeSocketGeometry for instance). This does not happen for all classes. For instance, trying to register the class NodeSocket simply produces an error message in the console stating that this action is not possible as the class is already registered.

See the file below containing a script triggering the crash. The crash file is also provided.

Step to reproduce the error

Open .blend file
Run the script

FYI: Replacing the 'official' Radeon ProRender 3.5.0 with the later 'unofficial' 3.5.2 version fixed this '#103055: Blender 3.4 Crashes upon exit' issue for me -- although I had to start Blender in the factory default mode in order to uninstall the offending add-on (otherwise, attempting to disable it crashed Blender on the spot).
