Sleep data is no longer recording on the Health app of my Apple devices

I have an iPhone 13 Pro and Apple Watch 10.

I have used the sleep section of the health app and have been using sleep data since I purchased the watch but after the recent updates on both the watch and phone in the past week the sleep data is no longer recording.

I don’t use alarms etc and havnt touched any other settings. I have never set sleep times etc as I have horrendous insomnia so don’t have a regular sleep pattern.

Any ideas? I really need the sleep data logging as I need it for monitoring for GP.
