Epic Games Launcher got stuck with preparing on Mac OS

Hi folks,

I did not find a similar topic if it was already created.

I moved from my old mac pro to a new one. I installed the Epic Games Launcher from scratch and the problem is that hangs with preparing. I tried to clean up the installation but it did not help.

It would be great if someone can share a workaround on how to fix this issue.
