File not loading (404 error)

A file (which I created) is no longer loading. I can preview the thumbnail in my main menu when I search for it but am unable to load it, and am told “If you expected to see a file here you may not have permission to access it. Please ask the owner to update the file permissions and try again.”

I’ve tried deleting figma, logging out of the browser and clearing my cache via Terminal but this hasn’t worked. Other users in my org are unable to access the file either.
