Rough or wrinkled surfaces in Grey Resin

I am having trouble with this problem. Certain part of area of the object gets very rough or appears wrinkles.
Also cleaned the window properly and stirred the resin thoroughly before print, still cannot get rid of the problem.
Could it that the Grey Resin I am using is expired or duplicate? See the Image below.

Did you check for dust/grease on the mirrors?

Try running an optics test and share the picture.

Can you please send me the link of the file for optic test.
