The app appears to have a memory corruption bug. Try enabling exploit protection compatibility mode for it in the app specific settings in the Settings app.

@andreasd083 There's a bug in the Hermes runtime used by the app. It doesn't properly account for the stack guard size. The library may need to be updated.

We've worked around it for the next release and have filed it here:

facebook/hermes#1535

Has been worked around on our end in the latest release. It's a bug outside our control though. It seems to be a combination of an app bug with a Hermes compatibility issue with Android.

The app is very buggy and the developer needs to fix it.

Does the app work for you at least part of the time?

It could be because of the stack probes being added but that's definitely not going to be removed. The app needs to update to a fixed version of React Native. You'll need to talk to them. We'll be adding back the 64k stack guard once we have confirmation the React Native patch has shipped.

The revert for the 64k stack guard was undone for Android 15 and will be added back. This should work again in the next release later today.
