OCLP, Monterey, external SSD, Migration Assistant issues

Hoping someone may have some advice?

Have a Late 2013 iMac that I use with an external 2TB Crucial X8 SSD running Catalina as the boot drive.

Decided to try OCLP. First time I just installed Monterey over Catalina. On boot the progress bar would get about halfway and hang.

Decided to wipe the drive. Install Monterey and then go through Migration Assistant and reinstall everything.

Monterey installation went fine. Updated OpenCore and installed root patches.

Then I started Migration. All loaded. But on boot the iMac would just go into a boot loop. Tried to load the boot picker and select EFI, then the drive, but the same issue happened.

Wondered if it was down to Migration Assistant overwriting the installed OCLP app with the old version on backup. So wiped the drive, reinstalled the OS and this time when I launched Migration Assistant I unchecked Applications. But the same issue happened.

So now I am back to wiping the drive, reinstalled Monterey and updated OCLP.

Before I go any further does anyone have any advice?
