Trouble opening Substance Painter

hi.

when opening substance painter i am immediately given this error

i have tried quite literally everything that i can find in forums, youtube etc

have deleted and redownloaded creative cloud, used the clean tool, updated c++ redistrobutables, logged iout and back in, deleted the app, restarted my computer and all of those at once. it is getting to the point where this is quite frankly a joke. a product so industry standard and expensive should not be prone to such issues. i have a deadline i need to meet tommorrow and am running out of options.

help would be very appreciated
