What is happening here?

Brand new Prusa Core One (Factory assembled) and Ive had one successful print off of it.  I have attempted to print this part now 6 times.  Different Prusa slicer settings (with supports, without supports, 10mm, 15mm, 20mm, 25mm) All fail.  This is the tool box listed on Printables that goes into the side compartment of the Prusa Core One.  I've run a benchy and the crazy fast benchy from the thumb drive that comes with the printer with minimal issues, but they didn't look as good as I expected.  For a new machine with less than 5 hours print time on it, it's kind of disappointing.  I've reverted to my Mk3S+ for now printing some of the other parts of this build (WITH NO PROBLEMS), but some are too large and need to be printed on the Core One.

Just a note: The first layer prints beautifully, nice adhesion and smooth surface.  Then when the additional layers get added, it starts to sound like crap like it's dragging and then after a couple hours looks like the above.

I have recalibrated the printer as far as I can tell.  It went through the whole process where I had to touch the print head and all that, and reran the print to the same messy outcome.

Any help would be appreciated.

RE:

Wet filament. Needs to go into a filament dryer. If you don't already own one I recommend you do.

RE: What is happening here?

BTW, what type of filament is this? Is it Nylon (PA)?
