Transforming a selection blurs object - plz help!!

I am having this issue where when I make a selection and use the transform tool, it blurs the object i am transforming. I have tried unchecking "anti-alias" in the selection Tool option bar, changing the interpoleration method to Nearest Neighbor, and changing dpi to 1000. None of that worked.

It used to work on Photoshop CC 2016 but i just bought the latest ver of photoshop and it doesnt work anymore!! whyy?

Before transform - nice and crisp

After Transform - Rotated... Look at all the messed up edges! it used to stay all nice and crisp like in the first photo after rotation!! why is this happening 😞
