Unable to edit Assets

Hi there, Recently I started a new project with a blank template. I was playing around with few of the assets already provided by epic games, I by mistake added asset into the project and I wanted to reverse my action so I clicked ctrl + z since than when ever I try to add a asset into the project I get prompted with a error which says “Unable to edit Assets”. I don’t know any fix for the issue but anyone knows please feel free to write the solution in the comments, I’ll really appreciate the help!

Are you still unable to drag in other FN assets into your project? You an also just select any assets you have in there and select them and hit the delete key to remove them.
