Hello everybody,
I have changed my computer for newer one, just installed fresh Windows 10 home 21H1, and latest version of Ultimaker Cura, I am using two monitors and experiencing problem. When I start program first time all is going fine and as long as I am running program on primary monitor it works fine. But if I move it to second screen and close program, it will not start again - it freezes on loading application window. Reading this thread I did find that it is enough to delete window_left and window_top positions from cura.cfg file and it start again. what is going on? and how to fix it. Temporarily I created on my desktop to Cura.cfg so I can quickly open it and force it to start, but it is only work around.
