Why does Command H does not hide Photoshop anymore?

Using Photoshop 27.4.0, Mac Tahoe 26.4, using my computer when working in Photoshop.  I used to be able to use Command H to hide the application as I worked between LR and Ps.  That shortcut continues to work on my older computer, on my new laptop, but for some reason no longer works on my Mac Mini.  The only way I can minimize it is to click on the yellow circle in top left corner.  I’ve gone into Keyboard Shortcuts, to View > Extras which shows the Command symbol+H.  How do I get the shortcut back the way I want it to work? Thanks in advance.
