I’m going to have to second hedgehog’s ideas of cleaning your bed and drying your tpu. Your filament says it should be good for a nozzle temp of 220-240, so I would expect stringing at 235, but it sounds like you are experiencing something a bit more extreme than “some” stringing.
Fair warning, the naked fat guy with the bow and arrow is not Cupid. He is just an exhibitionist. An arrow to the heart will NOT make you fall in love.
