Bug description

App immideatelly closes on an iOS 18-phone (fresh install on new phone). Seems very similar to #5796, but since that seems fixed it may be a different issue when installing fresh on iOS 18.

Steps to reproduce

• Install app fresh from App Store
• Tap the app icon

Actual result: Crashes/Closes instantly

Expected result: App should open

Screenshots

Device info

Device: iPhone 15 Pro Max

iOS version: 18.0

I also get the same issue, also on an iPhone 15 Pro Max

Same issue, lost all messages conversations and contacts trying to uninstall and reinstall. WTF devs????!!!!

Managed to get out debug log and see that it segfaults seemingly due to accessing an instance of a class that is not available.

The crash report indicates you're running an iOS18 beta - could you update to the released version of iOS 18.0 and see if this helps?

@pete-signal Funny, that did the trick. I did see it also in the IPS-file and I was surprised of it myself. I checked several times in the update-dialog if Beta was activated or if there was an update after seeing it but only yesterday it showed another update.

To the others (@antoinedesp @katosdev) having the same problem: Check again, maybe there was something borked up in the roll-out to your phones as well (or accidentally having Beta activated) and something went wrong when you updated previously. It works for me now.
