How to debug high CPU usage -> hang

I'm editing in ReST mode, Windows 11, emacs 28.1.

Occasionally, I want to jump (search, etc.) and the CPU usage jumps and emacs hangs. I suspect a font-lock issue.

I fixed one by bisecting the text, then changing a table type. Now I have another.

Is there a general way to debug?
