"Cannot charge my macbook: [...[I have a 2019 macbook air and it is not charging. I have never used another charger and I've had it for the last 6 months only. It simply will not charge and the battery has completely drained out already. I have tried different outlets with no success."

Go Here: If your Mac battery won't charge - Apple Support
Perhaps this is a Faulty Device?
If the above link is of no success, then contact Apple Support, and have them take a look at your Mac. You have a one-year out-of-the-box limited-warranty. So make use of it, if you have the option. Apple would send you a box; you'd ship the Mac out to them; they'll ship it back to you fixed anew.
Apple Phone Support:
Note: Waiting on the phone may take a bit, due to high call volumes. So, just stay on the line, and they'll be with you :)
