Failed to Map Driver

[null-lnp]

After boot, valthrun driver fails to map with Error: Mapping callback has never been called. I've checked sigs on bootmgfw.efi, seems all is ok but still doesn't seem to work.

For context, after fails, F10 doesn't work either and I'm forced to remove USB and manually turn off my computer.

SB is off
TPM is off

Tested on both valthrun-driver.sys and my own crafted driver with no imports, etc. both had same result.
