[Feature] Improved error handling of a bad folder structure

[calebsmithdev]

Is your feature request related to a problem? Please describe.
This is related to the initial project scan and immediate failing when the folder structure is setup incorrectly. In my case, I had the folder mounted but did not have a roms folder inside each platform.

Describe the solution you'd like
Instead of showing an empty error message (API resulted in a 500), show another type of error message to confirm a 500, or catch the error to show a more relevant message.

Additional context
I do not have the original log now with the failed messaging, but it was related to the function get_roms when trying to retrieve the roms for the first platform.
