Shutdown segfault with PySide 6.8.1.1

[markfinal]

Have seen this regularly on macOS.
Repro steps:

• Open Cruiz
• Open a recipe.
• Close Cruiz

Looks like this

Certainly upgrading to PySide 6.8.2 I've not seen the same segfault after several tests.

Unfortunately 6.8.2 regressed in the .pyi files, at least for QProcess.

I've so far not seen this in 6.8.3, and I had asked for the .pyi files to be fixed too.
