Using Cryptomator with PCloud Rewind

I am using Cryptomator with PCloud. A file became corrupted and the last back up copy I have is July (my bad). With PCloud you can Rewind to an earlier version of the file, e.g.last week.
My question is: if I use the Rewind to earlier versions of my encrypted files, how do I then open them? I have found a file that was modified on a relevant date so I have copied this into a Cryptomator vault but it is an empty file.

Hope this makes sense.

The easiest thing is it to overwrite the ciphertext file using in the exact same path, then you should see the updated content if the file wasn’t moved in the meantime.
