Error Reading Archive When Opening Any Rhino File(Rhino 5)

Today, When I open any Rhino file, I always get the “error reading archive” , I don’t know what’s wrong, Also, sometimes the opening process just stuck and I have to reopen the file.But when I am able to open the file successfully, it seems to work just fine.
What’s the problem and what can I do to fix it? I am a bit worried about the problem getting worse.Thanks a lot0

Please create a new file, add a box and save it, then attach it to a reply in this thread. We can then investigate.

Hello - also, please try opening Rhino, disabling VRay and TSplines and any other non-default plugins in Options > Plugins, then restart Rhino and open one of these files - any different?
