You are using Mac.
From the help files.

Thank you! Got it.

@Box is right but sadly my experience is that it is no longer reliable. I suspect it is a Mac thing dating back to version 2020 or 2021. Lots of things to do with standard icons no longer work consistently. Sometimes they do but mostly they don’t. It’s quite annoying, especially when you have invoked the Erase command and are seeing a standard pointer. You start trying to select something and you erase it instead. Not good.
