Hi every one,
I got the same issue as you today.
Context: I plugged an additionnal screen while Fusion 360 and Cura were launched.
I uninstalled the v 4.0 then install the 4.1.. Pb still present.
Then I went to the folder were Cura.exe is (C:\Program Files\Ultimaker Cura 4.1), Clic right on Cura.exe and select 'Solve compatibility problems' from the menu.
Then I selected the option "try recommanded parameters"... After few seconds Cura 4.1 launched succesfully.
Hope this 'repare' will last and hope this will help you also.
