Is this pCloud syncronization problem or Obsidian Bug?

Steps to reproduce

I create a new note in obsidian. I put some drawings in the note (same behaviour with text). You can see that, as obsidian autosave the note the size increase. So after a while when pcloud syncronizes the file, the empty file comes back and when opening the note it is empty. It happens the same when i modify old notes, so any progress is lost.

Expected result

A nice syncronization. Of course this system has worked perfectly until last week, when started to fail. (Update from both obsidian and pcloud)

Actual result

The empty new file is restored (or the previously saved file) and any progress is lost

Environment

  • Operating system: Windows 11 and pcloud
