Rebuild of App doesn't work after adding a BLOOM book

Good morning. In november I made an app, and today I added a book to that app. The book was exported from Bloom (with sound).
After the building of the app, I can not open it well in Bluestacks or on my phone. It will open quickly (white screen, nothing on it) and close again. After removing the extra book the problem stays.
I tried rebuilding another app, and that still works.
I did not update my RAB to the newest version.

@Bep if you can send me a copy of your project and let me know a link by personal message, I’ll have a look at it.
