Update June 25.5 too many issues

i am a very beginner and I regret updating it today. I can't work at all

So many small issues that i cant even properly explain

Keyframe animation is not working properly. Very very big issue

Selecting a keyframes deselcts the object instead of showing the path controllers

Selecting keyframe outside of composition boundary disappears the object

Can't select the controllers by dragging or deselect the contollers by dragging mouse or even by click shift
