Issue with powering ESP32 Dev Module with 5V regulator(7805) from 12V power supply

I'll repeat, and I know the cruel prospect of step-by-step is a soul-crusher around here, but you have to bust this all down to the 7805 and the ESP32. If that's good, then connect other modules till the trouble comes back. You should add the module and cycle power (sys re-boot) each time.
