MeetingBar: The application can't be opened. (Startup error)

Describe the bug

I have installed Meeting Bar using homebrew, and it runs just fine. However, if I restart my machine or log out and back in I get a cryptic error message “The application can’t be opened. -50”.

I then have to open Meeting Bar manually, which works fine.

To Reproduce

Install Meeting Bar, enable “Launch at Login” and then log out and back in again.

Expected behavior

This error should not appear and Meeting Bar should open on startup.

Additional context

I tried removing everything from launch agents, and all other startup items to eventually get to this. I can safely reproduce the error message on startup by uninstalling and reinstalling Meeting Bar.
