This message appears when the printer detects that the filament has run out during a print. The sensor has triggered a pause, and the printer is waiting for new filament to be inserted. The message shown is Filament runout during print, please insert new one.
This is a normal and expected function, triggered by the filament sensor to prevent failed prints when the spool runs out.
Error name: Filament runout
Error code: #31829 (CORE One) #35829 (CORE One L) #17829 (XL) #26829 (MK4S) #13829 (MK4) #27829 (MK3.9S) #21829 (MK3.9) #28829 (MK3.5S) #23829 (MK3.5) #12829 (MINI)
This feature helps protect long prints from failing due to an empty spool. If you encounter false runouts, check the filament sensor wiring, cleanliness, and whether the filament path is smooth and free of friction.

This article does not explain the steps or it what order. Am I doing something wrong? How is this feature supposed to work? How do I get the printer to load the filament when it is in this state?
Mine is not stuck as the extruder has backed out the filament to initiate the change

Had the exact same issue with my MK4S. Since my MK4S in a Prusa Enclosure, I loosened the PFTE tube and was able to (easily) remove the remaining piece of filament. Put the PTFE tube in again, fed the printer some new filament and it continued to load. My print continued , thankfully 😀
However, Prusa, this needs to be fixed ASAP !
