Can't see GIMP windows

[Tankred]

I have used GIMP for years. I upgraded to 3.0 and can't see any of the windows. I have it pinned to the taskbar ande tried to run it from there, nothing.
The services are running in Task Manager, both gdbus and GIMP. I deleted the sessionrc folder and restarted. I have reinstalled it many times. My graphics driver is up to date.
Here is what I have for my computer:

• Motherboard Name Asus ROG Maximus Z790 Dark Hero  (1 PCI-E x4, 2 PCI-E x16, 5 M.2, 4 DDR5 DIMM, Audio, Video, 2.5GbE LAN, 2 Thunderbolt 4, WiFi)
  
• Video Adapter NVIDIA GeForce RTX 4080 SUPER  (16376 MB)
  
• Operating System Microsoft Windows 11 Pro
  

 
and various normal things.
I am a total loss because I have never seen this and I am a computer technician/cybersecuritry analyst.

Please help as I have been thru almost every suggestion on Google!

Thanks

How many screens? There are Windows utilities that list the apps and their windows and let you manipulate them (move, restore...), did you try  any of these?
