Command 'SFDX: Authorize an Og' resulted in an error - What's happening?

I'm going through the Create a Hello World Lightning Web Component trail and am getting stuck at the point where I'm authorizing an Org. When I try to go through the simple steps in Visual Studio Code, I repeatedly get the following error message:

Command 'SFDX: Authorize an Og' resulted in an error

CLI Command process failed to start

... I can't get past this. Does anyone know the fix?

For context, I'm on a MacBook Pro running MacOS Sonoma 14.1.2 and have updated Java.
