Try drying your material in an oven overnight at 60 C. I think this is a moisture issue.

Very unusual problem! Have you inspected your extruder gear? Perhaps there is an obstruction or noticeable wear. Also I have found when changing filament that I’ve had to increase or decrease the temperature as not all filaments are the same quality.
Apart from that I would suggest reducing the distance between your extruder nozzle and heated bed just a tiny bit. Good luck!
