iOS 14.3 update on iPhone 8 just broke my cellular connection

I just updated my iPhone 8 from 14.2 to 14.3 today via the Finder on Mac running Catalina. After the installation completed I typed in my passcode to unlock the phone and the first message I see is "Cellular Update Failed. Your iPhone cannot make and receive calls or access cellular data until it has been updated". When I click "Learn More" the alert says "... iOS diagnostics detected an issue on your iPhone or iPad that might require repair."

Is there a software fix for this or is this really a hardware issue? My carrier is Verizon but I have not contacted them yet.
