The Prusa CORE One, CORE One L, and the Original Prusa XL, MK4/S, MK3.9/S are equipped with a loadcell. Thanks to this component, starting from firmware 6.0.0, the printer can detect whether the filament is stuck and not moving, for example when the nozzle is clogged.
If this is detected, the print pauses and the printer shows the message: "Stuck filament detected. The filament seems to be stuck. Please unload it from the extruder and load it again."
Once the unload button is pressed, the printer unloads the filament. After this, it prompts filament loading and resumes the print.
In case of multiple, repeated stuck filament detections in rapid succession, troubleshoot the loadcell and the components around it, using the steps in the dedicated loadcell troubleshooting article.
If loadcell troubleshooting does not improve the multiple and repeated detection, consider slight changes to temperature and slight reductions in the movements and extrusion movements. Those can be set individually through PrusaSlicer, or in a single print speed setting, mid-print, using the Tune menu.
It is possible to deactivate the stuck filament detection in LCD Menu -> Settings. Deactivating the detection comes with an increased risk of nozzle clogging.

THE MACHINE DOENSN'T ALLOW ME TO CONTINUE
Having read the help above I checked the calibration of the hotend load sensor, and the idler gate screws - all well. So, I changed the speed (slower) by selecting structural 0.2 and that solved the problem.
So I still don't know why the error occurred but I have a solution. Any ideas? PS: I am using a new roll of Prusa's PLA+.
The filament gets stuck every other print. But when it gets stuck, the printer keeps going with a rattling sound. I use original parts, original filament which came with the printer.
Few days old now, quite irritating. I am lost at the moment
