Game doesn't load after champ selection in MacOsX. All I see is a white screen with mouse on it.
Tried updating from MaxOsX Mojave to Catalina, tried reinstalling client in both operating systems, it didn't help. Game doesn't load anyway.
Recently I have had this bug in tutorial mission 2 (Power Up), but everything else worked fine. But starting from yesterday bug spreaded on every type of game (have tested Tutorial, Draft Pick & Practice Tool).
