Have you ever used
git bisect? If so, how did you use it? Did it help you find a problem which would otherwise be difficult to find? Story time, I guess?

Multiple times.
Typically on high frequented repositories. If there are a hundred commits (or more) each day, suddenly merged from multiple branches and shit starts to go weird, it is sometimes not clear when exactly it started to go south. So I write a test to reproduce the problem and then let git bisect checkout, run test, etc. until it can tell me which revision it first occurred in.
One time I also had to find out when a specific functionality in a microcontroller broke. I have forgotten, why we knew it worked before without having it covered in a test, though. The build-download-testrun-repeat-cycle took almost a day until it could pinpoint the revision. That was fun. But it nailed it to a single line and was right with it.
