Extruder always clogs up almost immediately after cleaning
I have had one roll of filament that did this.  I'd get a jam, clean it out, and immediately jam again.

I got the filament from a friend who had reported problems using it, but I thought, "I have a Prusa3D i3m3-mmu2, I can print with anything."  Unfortunately, I could not.

I threw away the filament (first I've ever jetisoned so callously), replaced the nozzle, and was back in business.

So, some filament just doesn't work.

But, there is another possible problem to check -- you might have a problem with stepper driver.  Even with low current from a blown driver or badly adjusted driver, the extruder motor may spin.  It may even be able to extrude filament into the air through the hot nozzle.  But, the torque may not be sufficient to force the molten plastic as it pushes against the build plate.  

Pushing the molten plastic against the build plate so that it "smooshes" well requires pressure, which comes from the push on the filament from the extruder gear, which comes from the torque of the motor, which comes from the current from the driver, which may be either blown or seriously mal-adjusted.
