Folks, the unit is working again. I followed some advise from a chess grand master and moved backward to solve this.
I re-assembled my GS step-by-step as when i first got it. I tried the different microSD cards I has flashed the image to with no luck. I got retro when I decided to flash the image onto a card using an older computer (running Windows 7). I popped that card into the GS, and KAPOW! it powered up! I tried the same thing with all of the other cards I had and they all booted up with no problems.
I don’t know if the whole problem was due to 1) my computer, 2) Windows 10 on my PC (which I recently updated), 3) the Etcher I was using, 4) the microSD card adapter, or 5) the image of ClockWorkOS I had.
P.S. - the chess grandmaster I was referring to was Maurice Ashley. Look up his TED-Ed video.
