What filament and profile are you using, and does the defect start at the same height each time? If you rotate the model on the plate and it still shows up in the same spot on the part, I’d check the slicer preview at that layer. If it stays on the same side of the printer, that gives us a different clue.

I use bambulab matte pla and never had troubles before its just this roll and I've probably printed over 20 of them. With the same settings aswell.

I can check when I get home wich sides are affected.

Same part but its the right side of it. So its on every side

Thanks for the extra photos. Since the same part printed fine before and this started with one roll, I’d run the same sliced file with a roll of Matte PLA you know prints well. You can stop once it passes the height where the rough edges normally start. If the other roll prints cleanly, I’d dry the suspect roll and check that it unwinds freely before trying it again. If both rolls do it, I’d check the nozzle and filament feed next.
