I've read all through the manual. I found out the issue has to do with one of the lens locking mechanisms.
The mechanism on the left does not descend fully into the body of the camera when the lens release button is pushed, so it catches and the lens is then only able to be removed with force (and sometimes even then I'm unable).
The metal on the left is what the aforementioned locking mechanism clicks in to. The problem arises when the lock doesn't descend into the camera and so the metal remains caught and due to the force used to remove the lens, a dent was formed in the plastic (as you can see right below the metal).
I don't know what to do about this....I managed to push the mechanism into the body of the camera and place a piece of tape over it so it could net ascend into place and get caught, but unless that part of the lens is locked correctly, the camera will not shoot. I am not opposed to taking the camera apart, but I wouldn't know where to begin.
