Best post your EFI (as a zip) so the boffins here can take a look.

If the system boots through OC and gets you to the Monterey installation wizard, then it is more likely to be an issue with the macOS Installer than the OC EFI.

Are you using the Off-Line installation method to install Monterey, i.e. full macOS Monterey installation App restored to USB pen drive (12GB+)?

If yes, you may need to erase the USB, delete the Monterey installation app, re-download the Monterey installation app, and recreate your USB installer. At least you know your OC EFI works and gets you to the installer. Getting a working EFI is usually the hardest part of installing macOS on a PC/laptop. Having issues in the installation process is not an uncommon occurrence.

If you want we can have a look at your EFI to see if it needs tweaking.
