After many many tries with above solutions, I finally had success with: Apple Watch > Settings > Bluetooth off/on and the error was gone! At least in my case ;-)

I've enabled "-com.apple.CoreData.SQLDebug 1" in my app target to see the sql logs and with Xcode 15b5 the app seems to loop (fetching infinite some sql data). Maybe that's the reason for your blocked UI too.

Had to remove the app completly from the device -> "Touch and hold the app icon on the Home Screen, ... tap Delete App".

Thank you for the hint. This is what I did. var url = secureCodingItem as? URL if url == nil { let data = secureCodingItem as? Data if let data, let absoluteString = String(data: data, encoding: .utf8) { url = URL(string: absoluteString) } }

Yep! After updating to 15.2. the intelligence is back!
