I have had issues like this before, a game I have played multiples times, out of nowhere no updates or anything just stops working on my lutris library and I can never fix it, do you all have some troubleshooting tips or know some troubleshooting guides?
I am still regularly surprised by what a restart can fix on every OS I have ever used or supported.
The difference between when MY Linux laptop has been running for a while (multiple days) and recently restarted is very noticeable. All the quirks disappear and everything is slightly smoother, and also for some reason I get faster WiFi?
