iBooks don’t open books on ipad

I can’t open my books or download/buy new ones on iPad mini4 with iOS 13.1.3

I tap on a book and nothing happens and the application freeze. On my iphone the iBooks works well.

I tried hard reset, delete the app and download again, sign out - sign in my apple id from icloud, updated the software on my ipad, turn wifi off and on.

Do you have any advice what can I do to reach my bought books?
