AMF: No slide values are usable!

Made a Catalina boot USB install disk. Installed latest Clover. Copied current config.plist and kexts over (working on Mojave right now). Booted from USB installer. Got this error:

AMF: No slide values are usable! Falling back to 0 with 0x0FF00000 bytes! ERROR allocating 0x... pages at 0x... alloc type 2 Couldn't allocate runtime area Boot failed: will sleep for 10 seconds before exiting...

So the bootloader isn't even booting. Looks like a memory allocation error. Newest aptiomemoryfixup installed, no change.

Any suggestions on how to proceed?
