The version of EfiGuard you're using is out of date (v1.2.1, current latest is v1.3). I'm mentioning this to address the original title (KMODE_EXCEPTION_NOT_HANDLED) as this was most likely caused by having HVCI enabled which v1.3 will now disable for you if needed.

Your updated issue (EfiDSEFix printing C000000D, meaning STATUS_INVALID_PARAMETER) also has an updated error description in v1.3, but what this basically comes down to is the DXE driver not being loaded, or else loaded incorrectly. EfiGuard itself does not return this status under any circumstance if it was loaded during boot.
