Silk PLA causes repeating clogging during printing

This Issue is plaguing me since around a year, everytime I try to print with Silk PLA (I have two different Silk PLAs, both exhibiting this behavior), after some time (usually around layer 3) I get hefty clogging.
Things that I tested so far
- e-steps
- temperature (190°C)
- retraction (0.5mm)
- extruder tension (minimal)
- enclosure (open for better cooling, to prevent potential heat creep)
- new hotend (Mosqito Magnum -> Rapido HF)
- ensuring that there is no tangling in the spool
- flowrate limiting (everything between 40mm³/s down to 1mm³/s)
- print speed (200mm/s down to 10mm/s)
- Bed temperature (70°C -> 60°C)

I never have these clogging issues while printing PETG, Non-Silk PLA or ASA. Even helping the extruder manually by applying pressure to the stepper gear doesn't alleviate the clogging immediately. With some perseverance it will start printing ok again for a few layers, then start clogging again. obviously, this is not a good thing because due to the clogging, the entire parts stability is catastrophic in the end.
