It could be caused by the check for updates function. Go to Tools -> Edit Parameters -> Plugins -> MeshRemodel and create new boolean key "CheckForUpdates" and set it to false.

Another possibility is shiboken6, which I understand to be for PySide6 only, but you are using Qt5, so I'm not sure why that is being listed in the segfault information. MeshRemodel does try to import shiboken6 inside a try/except block, and then imports shiboken2 when that fails. But if you have shiboken6 installed it would pick it up and use it. I should probably try to import shiboken2 first, and then resort to shiboken6 when that fails. I only use shiboken in one place with the GridSurface objects to check if the menu object passed in when creating the context menu is valid because I was getting random errors when debugging with pyzo, which might have been the culprit for the invalid menu objects where that only happened when running inside the pyzo shell. You could comment out the shiboken import and see if that prevents the crash if setting the CheckForUpdates flag to false doesn't solve the issue.

OK, I'll try this. I installed Shiboken6 with pip to try to compile FreeCAD with Qt6.

I'd be interested in seeing if putting the shiboken2 import in the try part of the clause and shiboken6 in the except part would make a difference. If you have both installed it should take shiboken2 first that way.

Deactivating the import completely works. Importing shiboken2 works.

I'd suggest to use PySide.__version_info__[0] to choose whether to import shiboken2 or shiboken6 (PySide from FreeCAD).

Should hopefully be fixed with https://github.com/mwganson/MeshRemodel/commit/9eb02e81e4b2148713f17ec5aa31a5aea97b8628
