Loading Issue / stuck at 78% (Mac)

Tried starting the game from the main menu where the loading screen won‘t get last 78%. When I cmd+q the game and try to reload, the first very first loading screen stays black after the logos and I can‘t reach the main menu. Sometimes that‘s how far it goes, sometimes it just needs its five minutes to get there again. I tried starting the game with lowest graphic settings and it get‘s stuck at 78% again.

Does anyone experience the same problem?
