Freeze during installation of Big Sur

Hi ! I'm actually trying to install Big Sur with Open core but I had issues during the installation of Big Sur. I get a freeze during the loading process. I heard that a patch "OsxAptioFix" could make it but I don't know where to find it and which one to choose.

Config :

Proc : Intel core I9 9900k

Motherboard : Z390 aorus pro

Graphics : RX590 nitro+
