I have used Linux as my main for 20 years, but I have a dedicated windows computer for games (hooked to my TV in the living room). A lot of my steam games work in Linux nowadays, but the windows computer just works without fuss. I use it ONLY for games and turn it off when I'm not playing anything.
Ironically some older games (older win95/98/XP era games) work better in Linux under wine or emulation...
I have also used a windows vm with gpu pass-through to play games on my Linux machine, though I'm sure a lot of your anti cheat would probably not allow that. I don't bother with that anymore since so many games work in Linux with proton.
For non-gaming use I feel that 99% of dual boot scenarios should probably just be virtual machines instead. I have a windows VM I fire up for proprietary software or work related stuff when necessary.
It seems to be affecting people who have multiple users at up on their device (this includes work profile, which runs as another user)
I'm on the January play system update but don't use work profiles or multiple users and have been okay, so far... Fingers crossed
