I am replacing some sockets with new sockets, that also contain USB charging receptacles. I have done this before. The question I have is with one of my outlets in my rec room (built in 2007, electrician did wiring originally).
Upon removal of one of the old grounded outlets, I noticed that the ground wire was connected to the ground screw AND the neutral screw. I thought this was odd. So I connected the new outlet the way I think it is supposed to be; two blacks to hot, two whites to neutral and one ground to ground. That resulted in that outlet and none of the downstream outlets working at all.
I reconnected the old outlet with the "proper" ground to see if that was the cause. Nope. It would not work at all (either outlet) unless the ground wire was connected to the neutral and the ground.
I am not sure if this is how it is supposed to be or why it is that way. I basically reinstalled the old receptacle how it was to avoid any problems but am not sure why it's like that. I also did install a new receptacle in the same room on another wall and it works perfectly. The ground was not wired to the neutral, only to the ground screw on that one.

Misusing ground as neutral is a code violation. It's the work of a hack electrician trying to get a job across the finish line, or other tradesman who severed a neutral by accident and hacked it so no one would notice.
I would search each receptacle box in that circuit for a reason for a neutral problem. Most wiring problems are at terminations. If you find none, I would find the next box back on the cable run (that is still hot), and disconnect the cable there. Whatever broke the neutral may have also nicked the hot.
If the electrician did this, then every connection in your house needs review. You know how to do receptacles!
