Is this a clog?
I've had my printer for months. I sometimes get a loud clicking noise on and off for my last 10 prints or so. Sometimes just one, sometimes a lot at about 1 second intervals. Then it goes away for 30 minutes or more and maybe comes back, maybe not. I opened up the part with the rollers and don't see any debris or wear on the rollers. Output is never affected. It's not from my spool - I can cut the filament so there's no spool and get the same noise. If I'm holding the filament between my fingers I can feel movement when I hear the noise. New symptom = I did a large print yesterday, +24 hours - worked great. Right after that on the next print no filament came out. I removed the filament and every time I try to add more it's get to about where the nozzle is and stops. I remove it with no problems and try again and it gets stuck at the same place. Every time.
Are these 2 separate issues and just 1 problem? And what might fix it (them?)
Help me Obi Wan Kenobi, you're my only hope.

Please help me out by downloading a model it's free and easy but really helps me out https://www.printables.com/@Hello_474427/models
A couple of things to try first:
It could be a partial clog.
Open the idler, heat to printing temperature and manually push some filament through the hotend. Finish with a fairly hard push and immediately pull the filament out.
If this doesn't help try a cold pull: https://help.prusa3d.com/article/cold-pull-mk3s-mk2-5s_2075
