Open with live server not in pop up menu

I’m doing the js course and have created the development environment and installed live server using Visual Studio Code on a windows 11 pro laptop. I was happily using the pop up men option ‘Open with live server’. I had to restart my laptop and now the option isn’t in the pop up menu I have clicked on Go Live in the blue bar at the bottom and it still doesn’t show in the pop up menu. Any help would be greatly appreciated.
