unable to revert to an earlier version of cloud document
Hello,
Yesterday I created a file, and today I'm unable to access it. I get a pop up "Sorry, we can't open this document."

I went to CC->Files-> Cloud documents. I wanted to revert to some earlier version of the document, but no success; the option "Revert"is absent, and all I can do is rename.

Also I checked earlier threads, and the user was recommended to contact the support team.
I reached out to the support team through chat, but the chatbot responds with, "We didn't find a supported product in your account."
Help would be much appreciated. I would like to know whether it's possible to recover the file, or not, so that I can continue my work asap.
