Performance settings keep reverting to default when I open AE

I don't know why this is happening, it started a few days ago, I normally have my disk cache size around 400GB and I have everything set up because I primarily work with large 3D renders and custom animations.

Everything is set up specifically for these types of comps but whenever I close AE and reopen everything is back to default. It also keeps showing me the tutorial pop ups as if I've only just downloaded it for the first time.

Anyone know a fix?
