MacOS Sequoia 15.3.1 - iMac Magic Keyboard issue

I recently updated to MacOS 15.3.1 and now am experiencing keyboard issues on my iMac \[M1\] Magic keyboard. When I try and use the shift key in conjunction with any of the numeric keys on the Bluetooth iMac Magic keyboard the corresponding symbol does not get produced. Instead the shift-number key combination seems to act more like a keyboard shortcut. For instance Shift-7 does not produce an ampersand, it instead brings me to the Systems Settings window. Very strange. Anyone else seeing similar behavior with their keyboards?
