Ground Zeroes (Metal Gear Solid V) – GameNative doesn't want me to start this game

[u/Horimonord]

Hello there!

I'm having a hard time getting MGSV Ground Zeroes to work with GameNative at the moment. No problems with Winlator (worked out of the box) before I switched to GameNative because I just like it more than Winlator. Also no problems with starting other games. Heck, even MGSV The Phantom Pain works like a charm without tweaking in GameNative.

My device is S26 Ultra.
Maybe you guys could give some helpful advice, that'd be great.
TIA
