I have not used an esp32, but I would suggest comparing your schematic to a nodemcu 32

Hint: In the POWER section, I protect the regulator against reverse bias when switching off, with a diode from output to input. There is always charge left in circuits.

Can you provide some of your insight to help me understand why there is a need for the regulator protection?

Thanks for the response. It is a first for me but the explanation makes sense.
