Scrivener crashes when you switch languages

If you use the standard ‘Shift + Alt’ combination, everything works fine. I use three languages, so I’ve set up ‘Ctrl+1/2/3’ to switch between them. However, when I try to switch the language using these shortcuts, Scrivener crashes.

I’ve removed all shortcuts associated with ‘Ctrl+number’ and tried different combinations to change the language, such as ‘Ctrl+number,’ ‘Ctrl+Shift+number,’ and ‘Shift+Alt+number.’ The program crashes specifically when I attempt to change the language. For example, I can press ‘Ctrl+8,’ and everything is okay, but as soon as I assign this combination for language switching and use it, the program crashes.

Scrivener version 3.1.5.1

I have reported the same problem twice till now.
