Can't take out and put in back widgets from a layout

I'm trying to shuffle widgets which are contained in a layout, so I'm trying to take them out and put them back again based on a position property. The problem is that if I run the attached code in PySide6 6.2.0 I get a "Process finished with exit code -1073741819 (0xC0000005)" crash, but If I run it using PySide2 5.15.2 it runs properly, so something has changed in PySide6 which causes the crash.
