5.2, W11.
Ran gramps.exe instead of grampsw.exe, user blue, as no issue of course with Grampsw.exe. 
Hit CTRL-C in the Gramps console to copy the following selected text:
gtk_tree_view_scroll_to_point: assertion ‘gtk_widget_get_realized (GTK_WIDGET (tree_view))’ failed
Turned out this assertion is known, however the CTRL-C in the console caused the following:
:
50837653: ERROR: grampsgui.py: line 664:
Gramps failed to start. Please report a bug about this.
This could be because of an error in a (third party) View on startup.
To use another view, don’t load a Family Tree, change view, and then load your Family Tree.
You can also change manually the startup view in the gramps.ini file
by changing the last-view parameter.

KeyboardInterrupt
Restarted Gramps.exe, and repro’d CTRL-C again, this time with no text in the console- same crash.
Looks like the combination in the console disrupts the Python Process in Windows, probably other CTRL combinations in Windows mentioned here will also do the job.
