Hello and welcome to Just Answerwhen you hear the 'pop' does its conicide with a sudden 'jerk' from the engine / driveline?
as if the clutch is sticking then this would make taking up the drive very jerky and difficult
and if so points to a faulty clutch or slave cylinder

If the rubber pad on the pedal is not a good fit then yes that could be making noises every time you press it
I'd suggest the next step is to get your head into the footwell so you can closely see and hear whats happening whilst operating the clutch with your hand
I've known this sort of thing before to be a broken / cracked pedal or pedal mount so carefully check the pedal and its pivot points for excessive movement
