I watched an episode of Law and Order SVU where the detectives march in and arrest a CEO of an insurance company because they kept denying something or other. Immersion ruined!

My bad. I’m on steam deck and have that option.

On the dayz game page where you would click play, click the settings cog on the right. Choose developer, then delete proton files.

I didn’t see this mentioned yet in the comments - have you tried going to developer settings and deleting proton files for the game?
