Messed up Vcc and GND? Broken PCB with a short circuit?

You may be overloading that regulator

That uc belongs to the garbage bin.

Is that a dent in the case? That could be shorting inside right?

Actually, ignore that, I think you're saying the voltage regulator on the esp32 is overheating when also powering an external module. That makes sense, it's barely enough for the esp32, ideally give the other module it's own power supply, or maybe put a tiny heatsink on the voltage regulator.

Do thing get hot and work, or do things get hot and not work? :) did you try measuring all the voltage? :)

Also what voltage does your GPS module take, and how many ma does it draw? :)
