I have screen time set on my device. Post the ios18 update, screen time app is not opening and it is crashing directly on the Home page.
On some other phone, I found that Screen Time opens okay if you don't have it setup for the time limit.
I am using IPhone 12.
Same for me on iPhone 15 Pro
Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. I'd greatly appreciate it if you could open a bug report, include a sysdiagnose and test project, and post the FB number here once you do.
