Pins are showing fine for me using Windows 10 PS version 21.1, did you by any chance hit Ctrl/CMD + H, that will hide the pins, if it's not that try resetting your preferences, you may want to backup your custom settings beforehand.
Thank you Ged!
Works a treat.
It happened to me on Mac. I restarted PS deleting prefs and everything came back to normal…
