They still do. There’s so much shit in Windows 10/11that could phone home and shut down your install if you don’t have a valid license, but Microsoft doesn’t actually give a shit if you have a license or not. They just want to make sure you have their botnet installed and not any other OS.
Often a combination of temp too high, not enough retraction, or water contaminated filament.
If the plastic in the hot end is too hot it will keep “running” out of the nozzle after retraction and you’ll get strings. Similarly if you don’t retract enough to actually pull plastic out of the nozzle during a rapid move, it will want to keep pushing thru. This is supported by the little blobs it leaves on that angled surface corner its travelling to when stringing, thats excess material squeezing out during its rapid moves then being left on that wall.
And if there’s water in your filament all bets are off on how it’ll behave.
215 is pretty warm for that esun PLA especially if you’re using the stock brass nozzle, try bumping that down to 205 or even 200, and increase your retraction speed and distance settings in prusaslicer a tiny amount (0.1mm distance, 2mm/s speed at a time until you see improvement is plenty)
Use a temperature calibration tower to test things out.
