...it's hard to tell what the exact problem is by watching at the photographs... please attach the project-file so we can see you printer and cura settings...

 

Did you manage to get a good print with one of the other profiles?

    I had the same because of Bowden tube. It swelled due to high temperature.

    It can also be:

    - gap between nozzle and Bowden tube 

    - too much retraction distance

    - nozzle clogged

    Yes, severely under-extruded.

    The Extruder steps/mm may need calibration.

    The printer and/or Cura have been set to Volumetric extrusion.

    As @brtzor says, it could be a problem with the printer.

    Both Mari and I have Ender 3 Pro's.  For myself it was always a blocked bowden tube at the hot end from heat creep.  I finally gave up and went with an all metal hot end.  Not perfect, but it's much much better.
