There isn't a poll response for "the game crashed before for me and still crashes", but that is what is happening for me.
This is with the free release on Android 12, running GrapheneOS, which features a hardened libc and malloc that *might* be a source of crashes (but only if the code is relying on undefined behavior).
Specifically, the game crashes when I try to save, despite having all requested permissions. This is regardless of whether Live2D is enabled or not.
