Getting stack on mid boot on OSX w single gpu passthrough.

sorry if it is the wrong subreddit but I am desperate and you seem like nice guys. anyway

____________________________________________________________________________________________________________Hey, Today I decided ill try installing OSX (catalina) on my amd pc
(
RX 5700 xt (amd)
Ryzen 5 3600
Asus Prime B550a - latests bios
16gb ram
Ubuntu 21.01 (latest kernel)
)

When booting to OSX using this github it successfully gets me to the desktop no problems but when I boot into that same disk again from virt-manager It gets stuck on this. Anything would be helpful, I tried searching the web for that problem but I couldn't understand anything about it. Thanks in advance !

This is where it gets stuck after choosing the drive catalina is Installed on.
