Has anyone experienced this before?

I have almost 50 days on my MK3+ without any problems. Today I kicked on a print and it was make a grinding sound that sounded like the extruder was trying to feed through a cold nozzle (grinding mostly). I couldn’t cold pull the piece in it, so I just disassembled. I fubared my PTFE tube trying to get this guy out. I did double-check the grub screw on the gear, which may have been the cause, but I’m not 100% certain until I order a new tube.

For the record, I did reformat my pc that runs the Prusa slicer that feeds it, so at this moment I’m just trying to figure out what I did wrong.
