Minecraft crashing after 10 seconds

My daughters both have 9th generation iPads, and they both play Minecraft regularly. Over the past few months, one of my daughters has consistently had issues with her Minecraft app. About once a week, she will open Minecraft and it will crash after being open for about 10 seconds (my other daughter has never had this issue). Usually, we try turning off her iPad and/or checking to see if her Minecraft app needs to be updated, and if that doesn’t work, we tell her to try again later. Most times, it will work normally again a few hours later. Starting yesterday, her Minecraft app doesn’t work at all. It crashes 5 seconds after she opens it, every time, and nothing fixes it. We even deleted the app completely and re-downloaded it. It deleted all of her worlds, but didn’t stop the immediate crashing.

my other daughter has the exact same iPad model, same internet connection, same everything, and she has never has this issue.

I don’t know what else to try! I noticed there is a software update available on the “problem iPad” so I’m updating the software (to 16.6) now, but I’m not getting my hopes up. This has been an on-and-off issue for months now!
