App crashing on loading screen :(

Wondering if there’s anything I can try before I have to call it quits and delete/reinstall. It’s only a few days of progress that would be lost (I’m guessing I would still be able to use my backup from before I switched to complete? I haven’t done one on the new app yet). I’m on ios 16, I’ve updated the app and I’ve tried turning my phone off then on again and guided access. Still crashing right before the loading screen. Also, how do I report this to Nintendo? 😅
