App crashing and not restoring purchases

Hello! I am trying to get help with my magic fingers app! I’ve used it for years and love it. I purchased the 20 effects add on and the drawing pack under my Apple ID last year but it’s not showing up after my most recent update. Also, on my iPad, since I did the update the app is totally crashing and won’t even open. I tried deleting the app and re-adding it, and nothing is working.

Please help!
