No boot after installing OCLP

Recently, I went to install Monterey on a Mac Pro 5,1 with OCLP. I downloaded OCLP, created the installer, and put it on a flash drive. Booting from it went fine (although I did need to reset the NVRAM with no hard drive because I don't have an EFI compatible graphics card to get to the boot menu), and I was able to go through the Monterey installer until it was almost done with the actual installing part, and then it 'crashed' to a circle with a line through it. Now, if I turn it on at all, it will simply turn off after a few minutes with no screen.
