App launches?

I have a TicWatch Pro 3 GPS. I just factory reset it and then played around uninstalling or disabling Mobvoi bloat and other stuff I didn't want.

At one point I disabled the wrong thing, and my app launcher didn't work at all. Just a black screen. Oops! So I re-enabled whatever it was, and then got a neat app launcher view I hadn't seen before. It looked like this. One app per row, icon then text, put favorites at top, followed the left curve of the watch screen.

Unfortunately, after a few hours, it disappeared and went back to what I'm used to. Two columns.

What did I do and how can I get it back?

EDIT: The one I liked was the standard WearOS launcher. It can be set via Settings -> Personalization -> Mobvoi launcher (toggle to off)
