Pixel on Android 14 hardlocks when getting instance in `/storage/emulated/0/Android/data/<appname>/files`

[Joehuu]

What happened?

Hello, I'm a regular contributor in osu! and we haven't updated since 11.5.0. Paper trail here: https://github.com/ppy/osu/pull/27920

This issue mentioned in the title is happening since https://github.com/realm/realm-dotnet/releases/tag/11.6.1. I have a Pixel 6a on Android 14, but this may affect any Pixel on Android 14. I am emphasizing Pixel because an osu! dev doesn't experience such an issue on a non-pixel on Android 14: https://github.com/ppy/osu/pull/27920#issuecomment-2068705204.

Also throwing in phones from users experiencing the issue the last time we bumped Realm >=11.6.1 to production: Xperia 1 V and AQUOS R8 pro. Those phones are capable of running Android 14. Ref: https://github.com/ppy/osu/discussions/27738

Repro steps

The below is similar to what I think osu! does in it's getConfiguration(): https://github.com/ppy/osu/blob/565107205c60f14488f1642011808d286d712c31/osu.Game/Database/RealmAccess.cs#L745 (namely storage.GetFullPath(filename ?? Filename, true)). If you want to test osu! side, remove that storage.GetFullPath() and it should run. Revert and it'll get stuck.

Apply this diff and run. It should get stuck at this line:

realm = Realm.GetInstance(@"/storage/emulated/0/Android/data/com.companyname.quickjournal/files/client.realm");
