Thermal Runaway on Polymaker PolyTerra PLA?!

I just got Polymaker's PolyTerra PLA and tried to print it on my Prusa MK3S+. About two minutes into the 3D Benchy, it started smoking, and the temperature was stuck at 190C on the screen. I turned off the printer and yanked the filament out. Nothing was damaged as far as I can tell, but I returned the filament. I'm still confused as how my Prusa MK3S+ didn't detect thermal Runaway. I am using an E3D v6 Hotend with a 30W Heater Cartridge. I am still using the same thermistor that came with my printer. How did my MK3S+ not detect this and almost start a fire?

I do not understand how that could only happen with one filament, so I would be careful.  I suspect you have a faulty part and I would have a chat with support.
