Hello, I'm running SolidWorks 2018 and for a while now, I haven't been able to see textures properly

I searched around on the forum, YouTube, and Reddit, but haven't found anything too helpful.

When I load a model (example below), the textures show up fine

But after the step "Update Graphics" the textures get replaced by a solid color (this happens for all objects with materials, including carbon fiber, wood, metals, orange juice, etc.)

When I click on a part, the textures will show up. They disappear once that part is deselected

Recently I tried to use Photoview 360 to get an integrated preview. In the past, the textures displayed properly, but now the only thing that appears to be rendered is the shadow. (Note that in a Photview360 Final Render in a separate window, textures are displayed normally)

If I zoom in/out or scroll quickly with the integrated preview enabled, I can see the textures before it disappears, almost as if it was underneath the solid color.

Is there a way to fix this?
