I have a popping noise when I open/close the driver side door. I tried spraying some WD40 on it but that actually made it worse. Anyone else have this issue and fixed it?

Is the noise coming from the latch area (rear) or hinge (front) side of the door?

What is the "it" onto which you sprayed the WD40?

Maybe we need an audio of the pop. Like a cork popping? More of a snap? Loud? Soft? high pitch, low pitch? A water drip kinda pop?

If it's coming from the door it's either related to air pressure or something lose. What happens when you close the door with the window open?

Very often, the pop sound when opening and closing the door is due to a faulty door check assembly. Replacing the door check is the usual solution.

Another thought: auto door locking being heard as a pop?

If its coming from the hinge, we had the same problem and had the door hinge replaced

This. There is a black plastic piece that goes between the door and the front door frame to prevent the door from closing on you when the car is not level or it is windy. If it becomes worn or damaged, it will make a popping or clicking sound. If you look carefully, you may even see that the very end of the plastic part that connects to the door frame is cracked where it surrounds the pin that holds it in place. These get damaged when the wind catches the door and it is over extended and cracks that plastic piece. It is a cheap part to replace but you need to remove the door panel to access the bolts on the door side. I have two that are doing that right now and because I know what it is and that they are still functioning for the most part, I am ignoring the noise. FYI, this is a very common GM part used on most of their cars.
