Qt 5.15 Apps crash suddenly on iPadOS 18

I have a strange behavior on iPad (with last version 18.2.1).
If I start my applications, after a few minutes the app crashes even if I don't do anything.
It only happens on iPad, while on iPhone (with last version 15.8.3), Android and Windows I have no problem.
If I start the code (created by Qt in release mode) from XCode it happens less frequently.
The problem is on OpenGL
