MacBook Pro M1 unlock with Apple Watch not working but with different account is working

Hello together,

my hardware, MacBook Pro with M1 chip and MacOS version 12.6, iPhone 14 and Apple Watch Series 5.

My problem in short is. Since a longer time I a can not unlock the MacBook with the Apple Watch. When I try to activate it i get the message "Your Mac was unable to communicate with your Apple Watch.

Make sure your Apple Watch is unlocked and on your wrist, and your iPhone is unlocked."

What I tried to fix it:

• In general often tried to check "unlock with Apple Watch"
• Logout and Login the Apple ID and Restart the MacBook
• Restart alle Devices
• Turning off Bluetooth, Wlan and on
• Checked that the same Wlan network
• Checked that it is the same AppleID
• Cleaning Auto Unlock in "Keychain Access" and Library

In Addition, I created a new User on the MacBook and connected it to my AppleID and there Unlock with Apple Watch is working but i don't geht it working with my main user on the Macbook. This looks like something is wrong with my user account on the Macbook. But What?

I'm happy to hear any ideas to fix it.
