Do you already have a solution for this problem?

I have the exact same problem. Did you find a solution @Emilia_S ?@Emilia_S

Interestingly, the issue seems to arise when NSColor.controlAccentColor is called anywhere in the code. Removing this reference resolves the issue. If you still need the accent color as a NSColor, you can use the following workaround // ❌ breaks SwiftUI accent color let color = NSColor.controlAccentColor // ✅ uses the SwiftUI accentColor as value let color = NSColor(.accentColor) I filed a radar under FB13688723

I have exactly the same issue. Forced to disable control center widgets until this get's resolved.

Same issue here, suddenly started happening while I haven't changed anything from code signing side.

I've been running into the exact same issue myself. It seems that simply referencing the constant ⁠NSUserActivityTypeLockedCameraCapture—even if it’s protected by an ⁠if #available check—causes a crash on devices running any iOS version below 18. Essentially, there's just no safe way to use that constant on iOS 18 and still maintain backward compatibility. This is definitely one of those cases where an Apple engineer needs to step in and provide a fix or an official workaround.
