I found the Solution...very simple, just delete the wireguardconfig that looks not very healthy in the flash drive. 
As you can see in the picture it does not look as a config should look like. 
 
 
As i explained first i forgott to extract the vpn config from the zipfile and uploaded the complete zipfile. 
So i think wireguard somehow tryied to build out of bits and bytes from the zip a vpn configuration and that in the picture is the result. 
My other VPNs were still funktional but i could not go to the adminpage of wireguard in the webgui. I think the webgui just coud not present those kind of symbols. 
 
Strange that there is no securitylayer that prevents somebody uploading a zipfile but thats how it is.
 
I hope - if somebody does the same mistake in the future like i did now - this post will help.
 
 

Hello, 
 
so simple Solution. The first i9 i had was not of good qualitiy. With the second i9 i got everything worked fine - except sometimes when the cpu got a big spike. 
Then i realised my PSU is to small - bought a oversized one 1200W Titanium and now everything works, nothing is crashing.
