USB Keyboard not working after sleep

I use my MacBook pro with the lid closed and two monitors. I have an external Mac USB keyboard, too. Before the Catalina upgrade, I was able to wake the computer using the external keyboard. Now, after I put the MacBook into Sleep then reconnect to my monitors & keyboard the keyboard does not work. The monitors work fine and the mouse can be used to wake the Mac. But the keyboard does not work until I perform a restart.

Any thoughts?

this exact question was open since 2019 for catalina.

same issue still exists in 2021 big-sur.
