Is there a way to recreate cryptomator index?

I run into a problem. I have 3 computers. on all I have one drive installed and fulla sync and cryptomator installed.
on two computers the content of the cryptomator folder is the same, on the third only one folder is wrong. These folder is empty.

Any idea what to do?

I created an additional folder and moved all files into it. Same thing. No files on the third computer.
