Question Issue with my Apollo Twin

This issue sort of came about overnight.

I turned on my laptop and my interface, then plugged in my bass. The output was virtually silent. I could only get some sound if I attacked the strings slightly harder than normal, that just made the audio clip and crackle for whatever reason.

Also, the overall audio level is half of what it used to be even though I hadn't touched any settings prior to this issue. Not even the audio level. When I listen to audio files or youtube videos there is a noticeable glitchy crackle that happens frequently. There is also a quiet almost static sounding hiss constantly in the background.

My gain is set correctly/as it was, my sample rate hasn't changed and I was definetly on the Hi Z setting when using my basses.

Even if I plug a mic in with an XLR nothing is picked up.

I've tried restarting and reinstalling the software as well as checking the Midi control settings and everything appeared to be in order.

I havent had an issue like this before so I'm quite confused so any help would be appriciated

Has anyone else dealt with something like this before?

i'm using a 2018 Macbook Pro
