It's looping here.

I've created the USB installer using a genuine iMac (late 2013, Catalina 10.15.7)
Then use that to edit your EFI.
To start with only install USBInjectAll.kext and enable it on your USB. Do not use the XhciPortLimit quirk or an SSDT-UIAC.
Test boot to see if the USB/XHCI looping continues. You should get further but not all USB ports will be active yet.
