Rough Surface at 1 Corner of Top Layer

Hey there friends!

So, I just got an Ender 3 V3 (Core XZ) recently, and it was working great until now. But now, whenever my print finishes, there’s one part on the top layer corner that feels rough to the touch. It’s only about 1cm long, and it seems to start where the hot end starts the top layer.

The issue exists only on 1 corner of the top layer.

Have you ever had this problem? Do you know how to fix it? I’ve tried calibrating the printer and resetting it, but that didn’t help.
