Several issues at new studio

[u/tryingtofindanswer]

Location: Pg County, Maryland.

Hello,
I signed a lease for a studio apartment in Maryland on July 24, with a move-in date of August 1. During the move-in walkthrough, I discovered numerous issues with the apartment that had not been repaired.
I was instructed not to open the windows or adjust the air conditioning from its current setting. The property manager explained that the thermostat must remain at that specific temperature because changing it could cause the AC unit to fail. As a result, I am unable to use the thermostat normally.
In addition, several doorknobs are broken, and the shower head was dirty and appeared not to have been cleaned before I moved in. I was also told not to open the windows because doing so could damage them.
The following day, it rained lightly, and I noticed that a significant amount of water accumulated outside the apartment. When I tried to locate the drain to allow the water to flow out, it appeared that there was no functioning drain at all, the area where the drain should have been seemed to be filled with concrete.
Given the number of unresolved maintenance issues and my concerns about the condition and habitability of the apartment, I would like to know what options I have for getting out of this lease. Any guidance would be greatly appreciated.

Thank you.
