Hello Snehansu Sekhar Paria, welcome to Microsoft Q&A forum.
Regarding the “Send Copy of Page” feature on iPad, recently many users have reported that tapping this button causes the OneNote app to crash, close automatically, or become unresponsive. This appears to be an unusual behavior following the latest OneNote update combined with the recent iPadOS update.

In the meantime, you can try update iPadOS to the latest version. Go to Settings > General > Software Update > and install any available updates. In earlier occurrences, updating to iPadOS 17.5.1 restored export behavior for some users.
We apologize for the inconvenience this has caused. Thank you for your understanding.
