Auto focus won’t work in viewfinder on Aperture priority mode

My camera (Canon Rebel t7i) won’t auto focus in manual or aperture priority mode in viewfinder. (It works perfectly in liveview)

Maybe it’s important to say that I’ve never shot in manual mode so I wanted to learn how to shoot in Aperture Priority mode. Auto focus isn’t working in viewfinder though. I used 2 different lenses (canon 50 mm 1.8 and the kit lens) It doesn’t work on both. I tried resetting the camera. Still nothing.

It does work in auto mode in the viewfinder.

Am I doing something wrong or is something broken?
