Anti Cheat Violation (Rumblebeard) (Proton)

[E4GLEyE]

Soo yeah this lovely message pops up as of late when I try to play, trying to hop on from Arch Linux, used to play from the Deck with no issues, but seems like something does not like something. Tried all the usual stuff, reinstalls validations, have the Proton EAC addition installed on steam... running out of ideas, anyone else ran into this? found any fixes perhaps? TY in advance, searching around yielded little to no results sadly :| Ah and also the Proton Experimental seems to be the only one that pops up the Login to Xbox properly.

Cheers.
