Crashes all the time after 3 years of using the app perfectly – neu.Annotate+ PDF Review

This app was perfect for what I was using it for, but now it crashes all the time. More specifically, I can't get it to open. After tapping on the icon, it starts to load, then freezes for about a minute and then shuts down. After many (sometimes over 10) attempts, it may open and then work perfectly until I close it and need to reopen on another day. So frustrating!
