I remember running into this issue back in the day. I think it happens when a mod corrupts game filed and I could only fix it by doing a clean reinstall and avoid the mod that was causing it. Reading through the comments on the Steam guide there are others who ran into this issue and at least one of them got it working by doing a clean install and trying again.
Over here stores are increasing their prices because people steal at the self-checkout. So they reduce costs by not having cashiers but then increase prices due to theft. Quite some logic.
You'd assume it's an easy balance to make: if (saving on cashiers - loss due to theft) > 0 implement self-checkout else don't implement.
Sure, you don't have to support it with updates indefinitely, but I think the possibility should exist to delist it so new people can't buy it but people who bought it before would still be able to download it (with no guarantee it will work).
I had something similar happen with playing Brotato on my Deck and PC, at some point there was a Steam Cloud error and my entire save got wiped. It's frustrating since you can't do anything after it has synced with all your devices. Steam Cloud is synced with your current saves and you can't go back in time to change it unless you still have access to the files.
So if you have a pc that has the game installed I'd boot the pc up without starting Steam and see if your save games are still there and copy them some place safe. Then let steam sync and move back the savegames and launch the game.
Also to add to this, you are disqualified from contributing code to the WINE project if you've seen parts of the Windows source code for this exact same reason.
I use Heroic if the game is from GoG or Epic and Lutris for the rest. I wouldn't bother with using just Wine since it's a lot easier to configure compatibility settings for each individual game with Heroic and Lutris. Both can use the same compatibility layers anyway.
I don't think Steam actually recommends any distro since some time anymore
I think they do by proxy since they only distribute it via .deb (and with Steam of course) and all games in the store that have a native Linux version mention some kind of Ubuntu version in their requirements as well. Which is funny since the Steam Deck doesn't even run Ubuntu.
It's like the olden times where illiterate people were asked to sign a contract that waived their rights and possessions while they were being told something else entirely.
