Epic Games Launcher starts in a black still image?

The following problem: I downloaded the Epic Games Launcher and the installation went well and so on. But when I start, then, strangely, the same thing always happens:

The launcher opens and a black still image (only the launcher) with three charging points opens.

I've tried everything to even copy the files from my host to my laptop and even that did not work.

I ask for help!

Kind regards

Specs?

The launcher can sometimes load quite a long time. Wait a few minutes. Do you have an internet connection?

Specs are top that is a Razer bade of 2017 and the internet connection also has 200mbit
That should not be it

Hmm. Try to start the launcher as an administrator. If that does not help, I would look for driver updates.

I already tried…
Which driver updates do you mean?

Prank that, it does not work on both PCs…
