If I understand correctly, you're struggling with isolation? If so, and if you have the time and resources for it, maybe finding a hobby, sports club, etc. in your area could help?
Hopefully he's just quiet. Having a derelict community for so long could be dangerous very dangerous, specially when it's expected for posts here to be legit.
Besides Flatpak, Heroic also has an official AppImage version, if the OP wants to have an even more portable program.
"Dumbfication" of songs is part of the reason I started listening a lot to rock. Quite a few rock bands seem to at least try to make something thoughtful.
But also been finding some musics outside of this niche too. Like, after some 10 years, I found again a music I quite enjoyed back then, Stromae's "House'Llelujah". I don't speak French so figuring the lyrics out is hard, but for this "DJ" type of music, besides the rhythm, it also appears to have a more thought out lyrics.
I prefer psychological horror over jumpscares by a long shot, so my recommendations are a bit slower than what people may recommend, but if it strikes your and your wife's fancy, here are them:
Dreaming Sarah, Wishing Sarah, Tanglewood, Parasite Eve, Wake Up (by Philosophic Games), UNLOVED, The Corruption Within.
To my knowledge, besides the newest updates not necessarily being as stable, but also, other softwares that interact with it would need time to adapt themselves to be sure they're as compatible as they were before. In a situation of constant updates, other software would always be on a situation of catching up, whereas updates that take a bit longer to land allow "for the dust to set down".
As much as GOG/CD Projekt have more than their fair share of problems, usually their versions of games work, can be preserved, don't require as much bloat, launchers included, and usually don't require 3rd party validation. And like others said, besides Wine and related, and installing through Steam as external games, you can also install stuff very easily through Heroic and the sort. So I'd say it's the better option indeed.
