I removed 4.12 from my new PC, installed 4.11 and copied the settings. Now I have 4.11 working on my new PC as it was on my old pc, so that's a relief, thank you for the tip.
But, I have a new problem. When I try to open a file Cura Slicer crashes. I can however drag files from file explorer to Cura, but when I try t open a file from the menue <File><Open> the app freezes and crashes after about 5 seconds.
Removed the app, reinstalled it, no resloution.
Any idea what can be wrong???
