Can't access friends

Like the title says. Next to my name is "5 friends", but it is not a hyperlink and I can't click on it. Desktop and App both don't work.

I had a "feed" show up of these friends' activities, went to Venmo someone, and then the feed was gone. In that feed was my abusive ex, so I'd kind of like to disassociate with him completely.

Any idea what's up? The FAQ is useless.
