What is the problem?
In order to update my Python, I took the easy method. I backed up my current Octoprint and copied it to my computer. Then I used a new sd card and Raspberry Pi Imager 2.0.6 to write a new image with the latest Octopi and Octoprint. After booting I get a message of 'No serial port found'. I put the original sd card back in the pi and it starts up just fine with a port of /dev/ttyUSB0. It doesn't seem like it should be this hard.
What did you already try to solve it?
I switched cables, used another sd card, tried safe mode, searched the forum for a similar issue.
Have you tried running in safe mode?
yes
Did running in safe mode solve the problem?
No

Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
OctoPrint: 1.11.6
OctoPi: 1.1.0
Raspberry Pi 3B v 1.2
Creality CR-10 Mini
Chrome browser

I don't think this is a hardware issue because I can pop the original sd card back in and everything works fine. I'm stuck.
Thanks for any help or suggestions.
