Why am I getting these bumps and whiskers on my CR-10S Pro V2 prints? (i.imgur.com)

I've been repairing a Creality CR-10S Pro V2 and can't figure out this persistent oddity. It prints spiral vases and benchies flawlessly, but regular 3D prints often have these pronounced bumps and thick whiskers sticking out. I think it's more than just Z seam blobs, I'm wondering if it's an issue with the wipe settings not working well in PrusaSlicer...

Here's another example of the issue: https://i.imgur.com/ZHssQWI.jpg

I'm using Kaaber transparent PETG, printing at 215/210 nozzle and 75 bed. I know this seems cool for PETG, but this brand tends to melt and ooze at anything hotter.

Here are my PrusaSlicer retraction settings, they are the default for this printer:

I tried slightly bumping the retraction to 6.5mm and 65mm/s, but it made no difference.

Any ideas what would cause this? I'm getting it while trying to print many parts of the honeycomb storage wall off printables.

Any chance there is moisture in the filament? I know I'm grasping at straws here...

Looks like moist filament to me too

I ran it in the drier the entire time, Sunlu S1 Plus. I've also tried some prints without it and saw no difference.

It was in my Sunlu S1 Plus drier the entire time.
