I was trying to use GPIO 5 for i2c communication and it did not work. I then noticed that setting GPIO5 to input in void setup()
(which is essentially what the wire library does) results in the board not executing the "loop()" function. What might be the problem?

I think that pin is the pin used for the SPI Flash chip
