I’m going to search something on the document page, but I got empty result.
Do you have any ad blocker extenensions enabled in a browser(AdGuard, uBlock Origin etc)?
I would investigate in that direction.
No, I have tried in 2 computer, one macbook, use safari, another one is a pc with windows 10, use firefox, both have no ad blocker, but same problem.
It hepped me to restart my computer, because I also encountered this today
