[SOLVED] Game fails to start “failed to connect”

I can successfully start the client and go through champion selection, but when the game is about to begin only a black screen is present and after a while a pop-up saying Failed to connect, retrying or reconnecting from the client does not seem to fix the issue. Is anyone else experiencing the same issue here or know a fix?

I use lutris and recently updated to the lutris-ge-lol-8.7.1 which seems to be the latest wine version available.
