early return on bad args rather than waiting for entire app to load

[hananbeer]

a minor annoyance I mistyped an argument and the entire app tries to load before failing on the bad arg and crashing.

a simple one liner fixed the issue by parsing arguments before anything else.

I really don't know anymore why testing fails. all it says is:

Launch unsuccessful
Stopping Web UI process with id 2182
Error: Process completed with exit code 1.

sorry for the absolute clutter for such a tiny commit 😓
