Tessellation/Distortion in Slicer

Suddenly everything I export is tessellated in my slicer. Everything was fine two days ago.
There has to be a setting I am missing. I had this problem before, but that was at least a year ago and I forget how it was resolved. I have been trying to figure this out for hours and hours now and am getting aggravated.

I was blaming the slicer for a while but past projects load fine.

None of my models are exporting smooth no matter how smooth I try to make them.
Please help. I’m going crazy
