This is why so many people find themselves in performative 1 on 1s: It's assumed that the time must be spent, so managers and reports alike start searching for things to fill up that time.
The best 1 on 1 formats I've had were quick and to the point. We cancelled or ended early if there was nothing to discuss that hadn't already been discussed.
The worst were a game of finding things to talk about for 50 minutes because some manager read a few management books and decided they must fill up the time to bond with employees. So we'd go through silly questions from lists from books or do bonding exercises while I had to pretend to smile and enjoy it.
