I first ran into this problem after trouble with the first beta of 4.3
After having multiple crashes on layout loading I decided to go for a fresh install. After doing this and waiting for my resources to download over the course of a weekend and then waiting for the library to index I found that I was unable to load up any note files, or create new ones. I also I can't load up any clippings file or create new ones either.
Was hoping that this beta would fix this but sadly it hasn't
