Activate is partly freezing after executing PyQT5 GUI

Hey community,

I have created a PyQT5 GUI and run it with the "ExecPythonScript"-block.

When I close the GUI the process still seems to be running in the background. The ribbons and the oml-command window are staying deactivated.

(the OML- commad window is also deactivated. It is just black because I use Activate on fedora, which is not supported)

I also provide the GUI script.

Best regards

Nils
