Steam makes OS unique modifications to the game, trying to share the same game drive between them causes an update war and corruption.

I’ve tried it a few times, never goes well long term. Generally, I partition the drive and only use windows for problematic games like pubg.

Also, if you enjoy workshop features in games with a native Linux version like Left4Dead 2 or Garry’s mod. I would recommend you force the windows version by selecting proton in the compatibility section under properties for that game. Some workshop mods don’t play nice on Linux and its like playing whack-a-mole solving it.
