I did a few things, not sure which it was that worked.
a.) I put the filament in my dryer overnight
b.) I was using a 3D Solex HardCore nozzle, but switched back to the UM3 AA Core.
c.) I went back to using UM3/Cura default profiles
magically, it started working again. I suspect that the material was just wet, maybe the 3DSolex core was also contributing. The 3D solex seems to have a tighter throat where the filament goes through, which seems to cause some issues with material swelling sometimes.

Did you have any further luck with printing your part with Polypropylene? I'm again also trying to print with it whereas results aren't great with default Cura settings. Adhesion is good but the print itself is just not good. Part I'm trying to print has some overhangs which I understand aren't that easy but even the first layer and plane horizontal ones seem to have issues. There also doesn't seem to be that much experience with PP in general so will be lots of trial - error I guess. In case you had any eureka moments, would appreciate sharing them. ?
