I'm experiencing the same thing. After updating yesterday and rebooting, Fedora Rawhide system became totally unbootable. Reinstalling everything with a USB yielded the same results. If it helps, my motherboard is an ASUS ROG STRIX B550-F GAMING (WIFI), with the most up to date BIOS installed.
The latest Fedora Rawhide ISO (2023-01-12) works fine, so grub2-2.06-75 fixed the issue.
