the Thing, that it doesn't happen on a New Profile leaves me suspicious.
so i did a little Research on my original/old/renamed Profile...
After copying File after File i found whats the Problem.
i can copy every file and Folder with no problem.
But if i copy the "Local State" File, the Animation appears EVERY TIME.
All Files after the named file doesn't result in problems

So i deleted it, and it was generated again on the next start. Now everything is fine. 🙂
