Hi,
having a similar problem with Affinity on any version, I tried all al the advises and suggestions in the threads and other web forums but its just frustrating to see that u must be either programmer and it expert as well when u actually want work as Fotographer.
I Freshley installed affinty and opend a raw file( .cr2/.nef ) Nikon and Canon ( single raw file ) everytime i hit "develop" the pic gets darker and the whole programm closes but there appears no crash report or similar.
Grafik diver is up to date ( Nvidia Quadro K620 )
In affinty settings it says i cant use open gl becuase : "The rquired Windows version is > Windows 10.0.19042
My detected version is Windows Pro 10.0.19042"
Ok ???
I hope u can help fix that Problem.
