I have an Arduino Mega connected in ESP-01 Wifi Module, I've tested the wifi module multiple times with a sample code (sending data to firebase) and its working fine but once I combine it with a pre-made code, the ESP-01 keeps restarting (connecting to wifi then suddenly disconnects and connect again)
I also have this in my serial:
