"Stuck on Boot After Installing macOS Sonoma on Unsupported MacBook with OpenCore"

I'm trying to install macOS Sonoma on an unsupported MacBook using OpenCore. Everything seemed to be going fine during the installation, but when the progress bar reached the end, the screen went black for a moment, then came back, and the Mac restarted itself.

Now, every time it reboots, the progress bar moves just a tiny bit before freezing. If I force a restart, I get an error message on the screen.

Do you have any idea what might be causing this issue?
