ESP32 and PCB type Relay

I don't seem to see buffering between the ESP32 and the relay in your breafboard setup. Usually (and preferred) an optocoupler for galvanic isolation or a transistor. I also don't see a flyback diode.

You should never connect a relay directly to any microcontroller; chances are that you have damaged your ESP32.
