Print fails with "frayed" ends (feddit.org)

Hi, I've tried to print a model plane for my father. It's this model, using this LW-PLA right after purchase.

As you can see in the image of this post, the print is going well until it reaches a certain layer, where the filament does not get deposited properly for the entire layer, only intermittently. The following layers then, of course, have the same problem and I get this failed print with these "frayed ends". Additional attempts failed the same way at a similar layer count.

If someone has some experience with lightweight PLA (LW-PLA) and knows what can be done to solve this, I and my father would greatly appreciate the help.

Thanks in advance.

Edit: Additional info: I'm using the PrusaSlicer files from the linked page. Edit2: The printer is Prusa Mk4.

To add to the temperature comments, are you using an enclosure? PLA is known to clog the nozzle when air temperature goes over 30deg Celsius or so. If yes, try keeping the enclosure doors open (at least partly) when printing PLA.

Yes, we have an enclosure, but that wasn't a problem so far. I'll add it to the things to try. Thank you. :)
