What's wrong with this prting?

[briesar]

How can I solve this and why does it happen? what's the type of error called? (see attached)I'm using a Anycubic Kobra 2 Max and I'm slicing using Prusa Slicer

The line is called a 'Z' seam, it happens where one layer ends and the next one starts.
There are settings in the slicer as to where you want it positioned.

In my Slicer Software there is an option to randomize location of seam to virtually make it invisible.
