We don't typically do report faital error for this. also the error is pretty
vague. if this is a nullptr it means the register doesn't have a type assigned
you should see many asserts that looks something like this:
`assert(InputType && "VReg has no type assigned");` please replace with an
assert and indicate the issue is with the register.
