Google Search Broken

Google search is causing some issues on Avast browser. It’s slow, and it will not let me go past page 1.

If I clicked page 2 or any other number, it just keeps loading page 1. I don’t have any extensions installed, I’ve deleted cache & cookies, but it’s still the same. No issues with other browsers.

My Avast browser search keeps getting hijacked, but I don’t know how?

I do not visit any dodgy sites, so I don’t know why this keeps happening.
