Hello,
Sorry to hear you are having issues. Unfortunately, Stardock do not "Call in", they do forum support right here in the forum.
We also need more information on your system.
- Windows 11 full version and OS Build number. Use Winver.exe.
- Fences 5 full version number.
- Open up your task manager and see if Fences have set to Startup twice. Fences need to have these startup to work properly. Refer screenshot below. Should look something like this.

Thank you.
Basj,
