I’ve had this issue before with cura years ago in certain features.

It sounds like you’ve tried multiple filament spools now, correct? Assuming at least one of them was somewhat new and dry I think that begins to rule out filament.

What slicer and firmware are you using? Even though cura/marlin didn’t have pressure advanced back when I ran into this it seemed like what was happening. The area impacted was either the start or the end of that layer.
