> Lmfaoooooooooo, so with `glibc-2.38_4`, current latest upstream version of glibc and Proton Experimental, EAC doesn't crash anymore, BUT it kicks you from game like a minute or so after start of the match cuz it fails anticheat authentication x)
> Gonna try with some other proton versions in a bit, but really not sure where to start with the failed authentication stuff, cuz there is nothing wrong in the eac logs now :/

Have you tried with more than one game ? (that you know it behavior before said update of glibc) or your game got updated? 
because what you're discribing was already something that was happening on some game (ie Vrchat, and that for at least as long as i started contributing to this issue)
for apex legend iirc it'd happen if you'd move manually the eac library from the proton eac inside the game folder
