I have a static LCD, a couple of other GPIOs configured as output and SWD which are all working fine. PA12 does not work when I configure it in output mode and i toggle the pin. I have tried using PA11 also with no success. The .ioc file of my project is attached. Thanks.

Do you do this in debugger? Read out and post all GPIOA registers.
Do you observe *directly* on the pin, e.g. using oscilloscope probe touching the pin?
What is connected to that pin, physically? Is this some kind of a "known good" board such as Nucleo or Disco (in which case make sure you removed all jumpers and solder bridges associated with this pin), or your board?
Thanks. I'm trying to develop a product with the chip... so it is on my PCB design. The pin is connected to an NPN transistor meant to control an active buzzer. I have removed this transistor so I can run a direct check on the GPIO.
The register clock for GPIOA is enabled as well as the clock for the other ports I'm using.
I'll check up on this... though I'm sure the GPIO is configured as output. I don't know if SWD and LCD being enabled on the other pins of the port is causing a conflict.
