--- Comment #5 from totinous.31@hotmail.fr --- I'm sorry but how do I do that "Use plain vanilla wine or plain staged wine only" or that "retest in 8.x wine/wine-staging, not a third party wine build" ?
I found that report Bug 52168 - League of Legends: RiotClientUxRender.exe crash and tried the solutions because the issue looks similar but it still doesn't work.
