I was able to play League of Legends (AppImg + dv9k version) two days ago. Yesterday I was getting an “Unable to connect to the authentication service” error so I first uninstalled the game from lutris then uninstalled wine, winetricks, lutris with all their dependencies using sudo eopkg rmf --purge wine wine-32bit-devel winetricks lutris
and then deleted all the related files in my system (such as config files). After that, I just reinstalled everything but now I get this:
I am confident that I have the dependencies on Arch Wiki installed and I’ve used sudo eopkg it wine wine-32bit-devel winetricks
which to my knowledge installs the wine dependencies.
