@BKeyport thanks for the response. It looks like my issue is actually with the Linux 12 / bookworm version of Raspbian I installed when rebuilding my MagicMirror, as opposed to the R-Pi 4 hardware.
In reading the Adafruit forums here: https://forums.adafruit.com/viewtopic.php?p=938344&hilit=Adafruit_Python_DHT#p938344 I find the official Adafruit response to someone with the same issues is that “DHT22 really sucks to use on linux” and … “you will be a lot happier just using the DHT20 and friends”, with a reference to an Adafruit web article at https://learn.adafruit.com/modern-replacements-for-dht11-dht22-sensors/overview.
In short, the advice is to just buy all new sensors for your Raspberry Pi installs. The OP pointed out that while he acknowledges the newer sensors may indeed be better, that " I spent a good amount of money buying and building, and for all of that to go away with an update really stinks! :( ".
I agree with him since I have probably five (5) DHT 11/22 sensors working on R-Pis, and while it looks like he found a way to upgrade all pip libraries and get it working again, it also appears to only be a matter of time until another update or upgrade of something breaks the system.
Again thanks for pointing me in the right direction.
