How to access the files that have been saved to disk and logseq?

When I was writing, a menu randomly popped up saying This file has been modified on the disk I selected the disk button at the bottom left corner and the second I did that all my notes vanished.

This happend again. This time when the menu popped up, I selected logseq at the bottom right corner, and MORE THAN HALF of my notes vanished.

My notes are really important to me, so I would really appreciate anyone recognizing this and giving me an explanation on it. So my main question is the title of this discussion.

I should also mention: I was using the android version of logseq.
