Can't open .JPG and Youtube is glitchy?

I've been trying to solve this issue for months and have found no answers. But its super annoying!

I can't open .jpgs in preview or in quickview on the Finder. (.png is fine, but not .jpg) Also playing YouTube videos gets really glitchy. Additionally, previewing audio files in the Finder is glitchy. I'm wondering if these are all related. Does anyone have any ides of why this might be? Thanks in advance.
