No Output/Input Sound

I have a MacBook Air and for the last few days when I use the volume there is no sound coming out and a small 'cancel' symbol that appears. I have tried everything from shutting off my Mac and turning it on, to killing the coreaudio, imputing commands on terminal, and nothing works. My bluetooth works fine which is so weird. I am not sure what else I can do.

MacBook Air (2018 – 2020)
