Unable to Unlock MacBook with Apple Watch Ultra

I am running macOS Tahoe 26.3, and I'm now unable to get my Apple Watch Ultra first generation to unlock my MacBook. I've tried some of the other remedies posted to no avail. Is anyone else having the same issue?

Apple Watch Ultra, watchOS 26

From Unlock your Mac with your Apple Watch - Apple Support :

If you're having difficulty getting Auto Unlock to work:

Open System Settings (or System Preferences) and turn off the Apple Watch setting described in the previous section. Then restart your Mac and turn the setting back on.
Install the latest macOS updates and watchOS updates.
Make sure that your Mac isn't using internet sharing or screen sharing, which are turned off by default.
