Textures Blurry, Particle Effects Not Working

While trying to solve another issue I was having in the editor, I realized that my Mats and Textures have gone blurry. Even in the blueprints, the display is blurry. An addition, particle effects aren’t working and my character is able to walk through custom static meshes. What is going on?

In the editor settings, did you tweak the quality settings to a lower value? if so, you may need to increase it back to “epic”
