Verify Catalog unhandled exception: System.IO.FileNotFoundException

[hegyre]

Hello,

RomSorter 6, with .NET 6.0.25, on Win10

Trying out the app. First thing I was to click on "Verify Catalog", which gave me the following error:

Then, after clicking Continue, all the buttons on the main screen are greyed out, and the only way to get back is to close the app and re-open it.
