What exactly solved this? I'm trying to figure it out.

I have forgotten. Please try:

pip3 install pyserial

I solved my issue (might have been different than yours): https://randomnerdtutorials.com/solved-failed-to-connect-to-esp32-timed-out-waiting-for-packet-header/

Basically, it was throwing tons of errors, but the important was that I either needed to hold the boot button down or connect a capacitor between the gnd and en pins to allow it to receive data properly.

Holding BOOT solved the upload issue for me on an Az Delivery Dev Kit. Thanks for sharing 🥳
