Minerva Author won’t reopen my generated stories

[uei-svg]

I have generated multiple Minerva Stories with Multiplex IF and H&E images and I have run into an issue. For the generated stories, and I can open and edit the .json files in Visual Studio Code. However, I’m unable to open those same .json files in Minerva Author to make edits there.

I wanted to ask if you could be of assistance with this. This issue is occurring on all the Minerva's that I have created. I have attached an image of the error message im recieving.
