I had the same issue. The hotend came with a larger sock, once I put that on, it helped a lot. After that it was working on my filament profiles to get the rest of the way there
Check your filament part cooling settings. The 4028 fan spits out a lot of air, I couldn't get any layers to stick with petg once that fan kicked on higher than 40%.
Exactly this, the sock they have in the pic is the wrong one
i had same problem turn off auto cooling in prusa slicer it ramps the fan up to full and you get that debris everywhere. It’s in the filament tab then set min fan to 30% mine worked fine after that
