You got more pics and details please?

I have this kind of issue with shitty white filament. Changing the filament with better quality ones solves the issue.

For this roll of filament, it looks like a retractation setting problem. When the head "jumps" across the hole, the printer retracts the filament to release the pressure. If the retractation setting it too high, it will starts the new slice with a lag in the pressure, leading to underextrusion.

You may try to calibrate your retractation setting. The value should be lower. You may get other artefacts (filament residue in the hole) but it's easy to clean.

You can make a "retractation tower" to get the best value.

I suggest it is too much retraction since the underextrusion happens at a spot where retraction should happen

Have you set up linear advance/pressure advance? I found it worked wonders with making sure the extruder gets back up to pressure after a retraction.

Looks like pretty classic underextrusion. Have you measured the filament diameter to see if it's exactly 1.75mm? Even 0.1mm is enough to start causing problems. It's prusament so should be good but worth looking! I can see underextrusion problems in more than just the problematic pillar, so worth playing with retraction and perhaps increasing temperature.

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.

It's called "Unretract underextrusion". It can be caused by problems in the hot end, or a problem with your settings (not extruding enough overall, retracting too much and molten material making its way into the cold-zone of the printhead), and other such things.
