ttkbootstrap in 3.9.4will not work

[nubbix]

I really love how this seems to work, but when trying this in VS Code using Python 3.9.4 on Windows. It does not work at all.
Keep getting this error message while using the default examples from the website.

So what or how do I fix this. Even tried to fix it using ChatGPT which only refer me back to the developer of ttkbootstrap.

Is it even possible to get to work?
