Hold CTRL+Z vs. Pressing CTRL+Z

[EDITS BY TYLER]

I had a question and was wondering if there was a potential change. I'm running Photoshop 2022 on my Mac OS. Currently, when I hold a shortcut, specifically COMMAND+Z, the application will continue to undo recent changes. The issue is it's very, very sensitive. For example, I'll try to undo just once with a single press, but it will end up undoing 2-3 changes. 

Has anyone else had this problem? Is there a potential fix?

My habit is to hold the Cmd key and just tap the Z key for each undo. Holding down any letter key causes it to repeat.

If the repeat is too fast, check your Mac System Preferences > Keyboard first.
