How to Locate information for app crashes to assist in diagnosis

I have apps that crash most days & have had this for years. I us an iPad Pro 11” Gen 3 on iPadOS 16.5. I would like to be able to get information on the problems to more accurately get a general clue of what the problem is.

for example, Libby is a library loan management app that allows reading or listening to eBooks or Audiobooks. Most of the time I listen. The app seems to crash multiple times most hours & seems to be getting worse.

I have looked at Analytics data & found only one entry for Libby. Is there a better way to find out what’s happening?

Thank you for your assistance.
