Horizon Desktop Editor scripts tab - unable to add a new script to the world

Hi was wondering if anyone else is having this issue - after most recent update.

I am trying to add a new script to the world, go to scripts tab, click the + sign, add title of script, it just stays saying adding script to the world and never finishes.  I can open up VS Code and it shows the name of the script I was trying to add, blank page, ready to add typescript.  I tried to add the script that had been generated by Llama, pressed save, but it's not showing up in the script list. Before the page would come up with some start code already placed. I could paste script from Llama, save and use it within the world.

I can't even see the title of the script file in the properties box where you click 'attach script' and the list of available scripts appears, no mention of the new script, even though I can save the named script from VS Code.

It was working fine before today's update. 

I can't add new scripts to the world until I can figure out why!  This is a world I have been working on for nearly two weeks, it is already published, has a number of scripts already working fine.  Any ideas before I tear out the rest of my hair! Thanks 😄
