Camera spinning in UE 4.20

I’ve finally jumped from 4.19 to 4.20 but camera there is spinning when I try to rotate it around some object. I didn’t have this bug in 4.19. Here’s what’s happening.

In 4.19 it goes like it works without problem.

Is it only me or it’s a bug that came back with this update? Cuz I heard it’s been happening before.
