I tried testing it on CachyOS through steam during the early beta testing and iirc I couldn’t get it to launch reliably even with proton experimental.
I’ll be picking it up and trying it again soon so I can update if they fixed it or if I can get it working
Prior to my advice below I’d recommend discussing this with a professional first based on some of your post history.
Once you get to a point where you are open to looking toward the future you could look into a ranger job in a national park/firewatch. It sounds pretty close to what you’re looking for being out in nature, disconnected from modern society, and sort of a frontier for you to conquer. However as it’s very isolated you really should get to a good place mentally first.
