RawkSD app menu "does not work"

[suprstarrd]

I currently do not own any Rock Band games. Until I can snag some, this might be challenging to debug.

Taken from AerialX#8:

I've tried to use the artifact built here on GitHub, but the app menu does not work. :-(

Could very well be a nothingburger since there's no further details or clarification (system information? region? game?).
