Error parsing arguments when I haven't provided any

[reedog117]

I'm receiving the following error just running setup_var.efi inside my EFI shell without any arguments (v2.2.0)

Error parsing arguments:
Error loading options: InvalidString(InteriorNul(14))

When I run ver inside my EFI shell I get this:

EFI Specification Revision : 2.5.0
EFI Vendor : EDK II BIOS ID:S1200SP.86B.03.01.5049.111220210556
EFI Revision : 1.0

I've also tried using various arguments and running commands like setup_var.efi 0x5D -n PcSetupGeneration to read values from my BIOS but I get the same InvalidString error.

I downloaded setup_var.efi directly from Github - could this be an issue with my EFI shell? How can I get around this?

This seems to be a similar issue to #7 (comment)
