This is still happening as of 1.19.1-rc1. It's very disturbing. I keep having to break my half slab floors to free cats. I've even stopped using slabs as floors because of it, which is a shame.
This is really jarring for any skyblock worlds.

This was several moments of problem, with no frame rate delays. I have a GeForce RTX 2070 video card.
I've added the log from that time period to this issue.
Yes... you are correct. Not a Bug. Gamemode 2 looks just like gamemode 0.
This was visible in previous beta releases. It's also visible in the latest release.
This is very consistent. I can reproduce the crash by moving my mouse pointer over one of the category labels as @unknown commented.
If I do not mouse over any of the yellow text/category labels I can use the game rules screen.
