OCLP Issues updating Mac Pro 5,1 to Sequoia

Hello,

I posted about this before but it kind of died with no real results. I thought I would try again with a more detailed post. I would really appreciate if anyone can help!

I am attempting to update my Mac Pro 5,1 to Sequoia using Open Core Legacy Patcher and I have encountered an issue. I will walk you through my process and hopefully I will be clear enough that you can help.

1. I created the installer with a brand new 32 GB flash drive using OCLP on my MBP.
2. I then built and installed Mac Pro 5,1 onto the flash drive using OCLP.
3. Pop the USB to my Mac 5,1 and start up holding the option key.
4. Once on the boot picker I select EFI Boot from the USB, as per the wiki guide.
5. After that, I select Install Sequoia from the USB. System boots to the 4 option recovery screen and I select install. Everything progresses normally and the computer restarts.
6. On the next restart, Apple Logo and progress bar appear and continues with no issue. System restarts.
7. Here the system starts up and I have two options: Install Seqouia or Mac HD as a boot drive. I select Mac HD. Screen goes dark, system never boots OS and eventually my monitors go into sleep mode.
8. Hold down power, restart, select Mac HD, same result ad infinitum.

I have rebuilt the installer and OCLP several times and started the process fresh, always with the same result. I am hoping I am missing some small detail that is just messing me up, but I have tried everything I can to trouble shoot this. I hold option with restart each time and make sure to pick the USB EFI boot, but nothing changes. I let the process run on its own, same result. Does anyone have any experience or insight on this issue? Thank you so much!
