MBP 8,1 (13" early 2011) Ventura won't boot with 8,1 OpenCore config installed to SSD but boots just fine with 9,2 OpenCore config on installer USB

My MBP 8,1 (13" early 2011) Ventura won't boot with 8,1 OpenCore config installed to SSD but boots just fine with 9,2 OpenCore config on installer USB.

I've tried reinstalling OpenCore to the EFI partition many times. It installs, reboots, and then hangs on the Apple loading screen about 1/3 of the way through the progress bar. The keyboard backlight lights up and is adjustable so hardware controls are partially there, but it never gets farther no matter how long I wait.

But if I plug in my Ventura install USB (built for a MBP 9,2), and boot from that EFI, and then choose my internal SSD as the boot device, it starts up in seconds.
