Ttkbootstrap and Ttkcreator crash with no error message when launched from command line

[electrovoyage]

Desktop (please complete the following information):

ttkbootstrap 1.10.1
OS: Windows 10

Describe the bug

When py -m ttkbootstrap or py -m ttkcreator is run at the command line, it does something for a couple of seconds and then crashes silently (no error message). Weirdly, ttkbootstrap still works when imported as a module.

To Reproduce

1. Open command prompt
2. Enter py -m ttkcreator or py -m ttkbootstrap
3. Press Enter
4. Crash without an error message

Expected behavior

Ttkcreator and ttkbootstrap should run

Already tried fix from #497, didn't help

[electrovoyage]

Ttkcreator appears to crash somewhere around here

[electrovoyage]

It actually seems like it crashes even earlier now

[electrovoyage]

Nevermind, still seems to crash somewhere inside DemoWidgets

This appears to be caused by #568
