The client apparently wants to be restarted, but that never happens.

Removing the text below from Config/LeagueClientSettings.yaml lets me log in, but this needs to be deleted again every time the league client is restarted.

Another log held some machine specific information which might be helpful, especially the windows N part (that's given me issues on other games before).
