Unable to open file

I have a rhino file that I have been working on for a while and now I don’t know what changed but when I try to open the file I get a popup that says “The document could not be opened, Try your operation again. If that fails, quit and relaunch the application and try again.” So I quit out of rhino and tried it again and it continues to say that. Is this a problem with the rhino application or with the file on my computer ?

try the command Rescue3dmFile, you can also post the file if its not too large directly here or via pm or via wetransfer or similar for somebody to try.
