This Windows experts never used it and call themself experts.
For me it brings back all missing features of the taskbar in Windows 11.
There will be a Windows 11 update which brings back this missing functions
and then there is no more a need for this tool.
With the official actual version I had many of this crashes.
I could not find any special action to reproduce it, it just happened.
It started after the last official update.
This setup fixed it for me.
No more crashes.
