If Sierra boots, if Mojave boots, you are both sides of the HFS+ to APFS divide so disk format can't be the issue. What exactly is happening when you try to boot High Sierra? A Verbose screen would be useful. The error you mention is a very early state of affairs, usually.
I can boot macOS Sierra, Mojave, Catalina and Big Sur with Opencore. But, I can't with High Sierra.
I have : attempting system restart...machreboot. What do I need to do to resolve this? Thanks for your help.

The error is what's in the title... It says a bit about my kexts before, but then it just attempts to reboot (and fails). MACHReboot? Never heard of it.
I had gotten a few errors before, but I fixed them. This one, I have no clue how. I'm pretty sure it's either kexts...
You can try to make a movie then capture from that movie the screen, set your camera for high refresh rate if possible.
Also, if you enable debug log all issues will be logged into a file
MACHreboot is usually associated with cpu power management being misconfigured
