GPA dropped a little bit during Junior year but have a ACT score of 32

Hi guys… I’m asian so keep that in mind

I’m a junior and I am in a weird situation.
So you see during the first semester of my Junior year I had an unweighted GPA of 3.92 and a weighted GPA of 4.0
However, I screwed up a class and my second semester GPA and it will probably be an unweighted GPA of 3.8something and a weighted GPA of 3.9something.
The good thing is that I received an ACT score of 32 and I would like to apply to Northwestern early decision (btw I live in Illinois).
Do you think the GPA drop will be of any problem?

Thanks.
