Spacebar won't work on my MacBook Pro after updating to the latest OS

If the problem persists after restarting, as leroydouglas suggested, try restarting in Safe Mode. Same thing?

What is the exact model of your mac and what OS version are you running?

Do all other keys work?

Try temporarily connecting an external keyboard. Does it show the same problem?

Check your Accessibility preferences and make sure that Full Keyboard Access is turned OFF.

You do not say what exact Mac?

Have you tried rebooting the machine?

The current stable release of Monterey including bug fixes, is macOS 12.5.1
