DeviceActivityCenter startMonitoring Error

I found that in iOS 18.5, DeviceActivityCenter startMonitoring cannot start multiple monitors, even if their names and periods are different, and restarting the phone cannot solve it. My app uses DeviceActivityCenter, which makes the entire function unusable. (I have less than 20 monitors)

I hope to get an operation guide that can make this phenomenon disappear temporarily so that I can inform my users
