Apple Watch series 3 sensors not working

I have an Apple Watch series 3.

Six days ago it was updated automatically to the latest update 7.6.1.

After that all sensors stopped working. Hart rate, step counter, activity, light doesn’t turn on when charging, display wake on wrist etc are not working.

Any idea how to fix this?

The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.
