No backlink is found

Obsidian stop showing me backlinks as if i just haven’t any of them.
I tried to restart obsidian and the PC, but to no avail.

Doesn’t know exactly how to reproduce this bug, but it related with workspace.json.
When I deleted workspace.json backlinks appeared again.
My PC sometimes freezes (not even react to REISUB) so sometimes I press “power off” button. I think it may be the reason why workspace.json doesn’t correspond to actual files.

It will be nice if workspace.json was automatically rebuild on each exit from obsidian.
In this case just restarting obsidian will fix everything.
