Confusing Issue Preventing Work from Being Done

I opened a Level to edit, and it just started automatically zooming in to the center of the stage. I tried zooming out, but for some reason it just continued to zoom in.

When trying to edit details of any object, immediately after selecting the value, it would deselect it, and start selecting things above it (like holding Tab, but in reverse).

This has been going on since Tuesday, and reinstalling it made no difference. This is a really confusing issue and I have no idea what could be causing it, does anyone know why this may be happening? This is causing UE4 to become unuseable for me.

Broken keyboard… Try un zooming ghen unplug your keyboard and see what happens.

tried this, didn’t make a difference
