Hi, guys,
I am a newbie at UE4. Today I downloaded and installed UE4 on my Mac (macOS Catalina, MacBook Pro 2015). After the first start I could use the program, after a restart I always get the following error.
I have already tried everything: Uninstalled several times, reinstalled, restarted and so on. The error comes over and over again.
Now I am a bit desperate and hope that someone can help me.
Best regards,
Markus
