Unable to create link for Aero Experience

Hi,

I was today working on a few experiences that I have been developing for a few weeks. Until today I have had no problems, but now I am both unable to create new links to experiences and to update existing ones. I am working with an educational account, but tried shifting the files to a personal account and have tried using a different device and it still is giving me the same error messages.

this is an urgent issue so would appreciate any help!!
