Question how can i make a quad oriental to the camera(view direction)?

i wonder if i can make a quad/mesh towards the camera/view always,and I caculate three rotations in three axis:

That's what i do in shader graph. i know is a silly way, but this is one i can image.
The three branches on right is the rotation.x, rotation.y and rotation.z.

And when i apply it to the rotate-vector3 function(the function is in the following image),sth goes wrong.

I found that the rotation on X axis is right, but when it comes to Y axis, only half of 360 degrees is right.
in this image, quad rotates rightly:

and in this situation, it goes wrong, and the rotation totally oppsite.

no matter if i use a 2*PI to subtract it or not, this strange problem happpens still.

English is not my first language, thank you for your patience!
