Hello Everyone, hope you all been doing well.

to keep short, I might i've found a work around the imcompatibility of proton with drivers fomated in ntfs, just move the prefix to a compatible driver and create a link folder in the ntfs formated drive.

Explanation and example:
When you install a game regardless of os, it installs in the same manner, in SteamLibrary folder it downloads in steamapps/downloading and then moves the files to steamapps/common/game
so in the end you have:
DriveName/:SteamLibrary/steamapps/common/game

but with proton a extra step, a folder with the id of the game/program is also created like this:
DriveName/:SteamLibrary/steamapps/compatdata/gameorprogamID

So using Asseto Corsa as a exemple, downloading a game with proton, theres 2 relevant directorys
DriveName/:SteamLibrary/steamapps/common/assettocorsa
DriveName/:SteamLibrary/steamapps/compatdata/244210

Solution:
Move the folder with the id in compatdata to a compatible drive and place a link in its place, like this
ext4drive/:244210_ext4_prefix // as long as no special permission is required in that folder it should be fine
ntfsdrive/:SteamLibrary/steamapps/compatdata/244210 //in this case the folder 244210 is a link to 244210_ext4_prefix

History:
recently i've been trying to play Assetto Corsa, and the game just refuse to start, no matter what i did, if i fixed one error another appeared until it just wont start with no errors, until I moved the prefix folder that was on a drive formated in ntfs and moved to a ext4 drive and created a link in the original folder, and it suddenly worked 1st try

Before doing that I had tested with proton 5 to 11 and hotfix and experimental as well as ge-proton10-34
