Question - Sink drain not draining

[newbhomeowner]

I moved in to a place a month and a half ago. I have a double vanity and one side has a sink drain that has an AC drain line connected. This side has been slow draining since moving in. I finally got to taking the pvc pipes and ptrap apart and it was horrendous; absolutely discgusting.

Anyways, I cleaned it out, put everything back to how it was previously with the o-rings. Now it not only does not drain, but everything is leaking. Water drains to a certain point and then it just fills the sink. I've tried taking it apart and putting it back together 3-4 times already to no avail. Does anyone have any insights? Do I just need to buy a new setup?

Thanks in advance!

Unhook the stopper and pull it out of the sink. It may be clogged with hair. If it isn't then you'll have to snake the drain going into the wall. Last option is to call a plumber.
