@Miech this solution doesn´t work for me :-( i have a brand new computer now... new processor new ram new mainboard new SSD ... only the gtx 1080 stayed and my two monitors... i have a brand new ssd and new windows 64 bit pro installed and still on this fresh installation cura 4.5 isn´t starting ... so it must have problems with nvidia / two monitor setup but like i said miech´s solution isn´´t fixing it for me :-(

cura 4.4.1 was also often not starting but 50 /50 it worked... now cura 4.5 or any new installation of 4.4.1 is not starting anymore at all. (uninstalled and installed several times ... used cc cleaner ... also deactivated a lot of stuff and tasks on startup but nothing helps) i think the only thing on the system i changed in the last weeks were fresh nvidia drivers... cura.log
