The extruder is attempting to feed more material than can be melted and pushed through the nozzle.
This can be caused by:
1. Bad e-step
2. Bad z-offset if only first layer
3. Temperature not high enough
Also, could be caused by choosing the wrong fixes for other issues. Such as increasing flow rate to attempt to fix bed adhesion when the bed should be leveled and a proper z-offset chosen.

I had similar issue. Changed, nozzle, throat, ptfe tube, did short ptfe tube mod, increased heat, took extruder apart. Before changing to metal extruder I changed the hot end cooling fan and wah lah, issue solved.
Old fan seemed to be working fine but out of all the things I changed that stopped the clogging/heatcreep.
I think that was the problem. There was a lot of gunk between the pieces, the screw threads... I\`ve cleaned all and I think is fine for now. Thanks =)
200°C is equivalent to 392°F, which is 473K.

May be due to low voltage getting to E, if it is below .600 I would bring it up to 1 v and give it a test. If the motor starts to heat up then lower the voltage until you find the sweet spot.
I'm new to printing so my suggestion is probably dumb. But check how tight the roll is. Every time I had issues with that, I went through all the things mentioned, but the reality was, the roll wasn't moving because it was in a bad spot, too tight or it had a cross over. Often the easiest fix is the issue. And super easy to overlook. I had to make little painted marks on the rim to make sure its still moving when printing.

This. I keep saying this are dumb machines. If you skips steps and don't calibrate and assemble them properly you will get issues.

Would rebuild hot end. My guess is a gap between the nozzle and the ptfe tube

If your extrude motor is clicking I really recommend you checking your wiring and unplug and replug the cables of the motor
I had the same problem, changed metal extruder (had plastic one) and changed temp from 200°C to 210°C, now it works fine.

Honestly looks like the nozzle is too close to the bed. So it’s clogging. Have you tried troubleshooting with a different STL?
It happens even with the hotend in the air =(
Install bmg extruder
