App will crash if settings is invalid

Updating AB

[X] Yes, I have updated AB and still experience this issue

What happened?

If the ABsettings.json file is somehow corrupted, or invalid. The app will crash without informing the user as to why. The app will also not log or tell the user what went wrong. I noticed this because my settings file somehow became like this:

{
    "current_bw_dir":

And when I tried to load the app it kept failing with no errors or log output. This happens in update_old_settings in settings.py when it tries to load up the settings file. The global except handler has not been setup at this point as well.

It will simply try to load and then fail with no output:

Relevant errors

We just need to update the code so that it will properly print out the exception. Something is hiding the error. I imagine it's probably one of those broad except handlers somewhere.
