Getting stop sign icon after following Linus's tutorial

I was about to install the system but when it tried to boot I just get a stop sign icon.
But it slowly spits out more text that is unable to be read.

The tutorial I followed: Apple won't like this... - Run MacOS on ANY PC

Recording of the boot up: https://www.youtube.com/watch?v=m16298PmNTI

I've done this 5 years ago on a physical system but I broke my computer (seemed to be unrepairable) while doing that.
That's why I wanted it to try it this way with GPU passthrough.

Also I've tried the `-f` and `-x` flag as well but the same output occurred.

Since I can't see any error in the output I have no idea where to look for an answer.

Am I missing something?
What am I supposed to do next?
