It's now May 2024. This is *still* not fixed as of hot fix 25.

macOS 14.4.1
DS4 controller attached via USB

Even with the addition of the disconnect second player option, its still very flaky as to whether connecting a controller, as a single player, makes the game split-screen and think a second player has joined. However that option is only present on the main menu.

A character creation dialog appears in the split, but the controller buttons are also split across the two screens. Impossible to use it in this condition.

A second player has not joined.

I press X to interact with an object, I'm prompted that another player is attempting to join.

A second player has not joined...

Switching characters (L2) prompts me that another player is attempting to join.

A second player has not joined, I cannot stress this enough!

All I want to do is play my single-player game with a controller. No split screens, no multiplayer.

I reported this as a bug through the proper channel back in September, received an acknowledgment, but nothing since.
