This has been going on in several versions including V23.2.0 (Build 69). Whenever I create a new shape layer in the timeline, say a rectangle, the handles would appear and then disappear. Immediately clicking out of that layer and back in will not make the handles appear. You will need to move the playhead further down the timeline in order for the handles to reappear. But that wouldn't be the "in" point you want the shape to be in, so you move the playhead again.
Top screenshot shows a rectangle shape layer with no fill. Playhead is at the beginning of the shape layer, but the handles for the shape are not appearing EVEN if the shape layer has been selected.
Second screenshot shows the playhead has been moved further into the rectangle shape layer in order for the handles to now appear. But that isn't the "in" point where I would make the shape adjustment so I have to move the playhead back to where it originally was.
Please fix to make the handles appear once the shape layer has been selected. Sometimes it does and sometimes it doesn't. You have to "play" around with it to make it appear.
