What if the earth were filled by vacuum inside it? What would happen?
Hypotheticals that don't make sense are not worth answering because it couldn't happen. That's like asking what if the oceans were made of jelly instead of water, or if clouds were made of cotton candy. It's a fantasy. No need to waste the brain cells thinking about it.
The ground would suddenly shake, and the sound of the largest Dyson vacuum thought possible would fill the air. Your intestines would be sucked out through your asshole into the center of the earth, until the almighty Dyson was filled and content.

It would attempt to collapse on itself(Unless it was made of a strong enough material that it wouldn't).
Also, gravity along with the vacuum would be forcing the earth to collapse, so there's that as well.

The cavity would immediately collapse because of gravity
