App GUI suddenly stopped loading

[allenerenee]

Describe the bug
I was in the middle of transferring my recipes from Gourmet Recipe Manager. After each recipe saved, the GUI would refresh and I'd have to scroll back down to the bottom to confirm where I was. This worked... right up until it tried to refresh and failed to reload. Now when I open the app all I see is the blank background window. Terminal output shows me this:

Checking for update
Update for version 0.8.3 is not available (latest version: 0.8.3, downgrade is disallowed).
checkForUpdatesAndNotify called, downloadPromise is null

To Reproduce
I'm afraid I haven't the foggiest - unless there's an upper limit on database size that I somehow already ran against?

Expected behavior
After GUI refresh, the menus and recipes should have reappeared
