Hairs on infill
This is not a moisture issue the filament was actively dried by a sunlu unit for 24 hours before the affected prints.
Using a Prusa Core One, this is on the default 0.2 Structural settings. It looks like little hairs sprouting off of the infill, with gaps in infill around them. My best guess is that infill is not adhering to the prior layer of infill but I have no idea how to fix that. Anyone seen this before? The benchy uses the same settings.
Double check you have sliced for the correct filament. If so, check your dryer is working properly.
Cheerio,

Is this PLA, PETG or another filament ?. Those messy infills are typical of PETG, specially if the filament isn't dry enough and you use a troublesome pattern like "grid".
It would help us to diagnose the issue if you uploaded the project file of this print job, because it contains all your settings. You can't upload directly the *.3mf file; first it needs to be compressed into a *.zip file. ( Don't ask why this forum won't accept *.3mf files... nobody knows. )

Solved! Solution was changing from cubic infill to gyroid and using structural (slower) over speed. Reverted back to default temperatures.
RE: Hairs on infill
I had similar issues with a print a few days ago using PLA and a 0.6mm nozzle, in my case I concluded my chamber was getting too warm and the previous layer had not cooled enough when the next layer was printed. I started to see fine hairs when moving between parts and eventually the print head lifted the previous layer when printing the next and that quickly escalates to a mess. Just shutting things down and waiting until the next morning when the workshop and printer was cooler solved this for me. In my case small parts worked but the larger part with more infill failed when the printer started to print infill faster failed. I print on a core one with advanced filtering system and the chamber cooling is simply not enough for PLA when the workshop temp climbs over 25C.
