[EDIT] if you have encountered the same problem then i’m sorry to say that i can’t tell you how i did it because i forgot about it, sorry
I downloaded the League client following the instructions on the r/leagueoflinux megathread and launched it using wine-lol, however, when launching the client instead of getting a login screen I get a black home screen with a blank user profile. (imgur link in comments because i can only post 2 links)
