I bought the Arkham trilogy this weekend (woo for sales!) and am finding some "interesting" issues - one of which has me stumped...

Arkham City - I start it up and get as far as that nVidia "Way it's meant to be played" tag... and then it crashes back to the desktop. I've tried the stuff here:

to no effect.

Running Windows 10 20H2 and all current patches.

Help!

EDIT and now it seems to be working! Little bit baffled but the only change I made was to change the permissions on the settings app to match that of the main game executable and then it launched properly. Bizzare.
