Stuck at First Loading Bar (after Booting Clover from USB)

Hi,
I have a problem. Whenever I try to start the catalina installer from my usb over clover, it stops right at the loading bar with the apple logo. I tried -v and -x and different nvidia options but had no luck with it, it's always the same. With -v and -x or without it gives me this picture which then stucks.
Anyone has a clue what might be the problem?
Do I maybe need to reinstall the usb with different settings then normal (like the tutorial)?
Thanks

PS: I'm booting from onboard...
