I see that your losing melt pressure on the resin and getting back filling in that area. Warm mold up, lower clamp and increase vents on the entire part; then shot as fast as possible ! TPV means there’s some cross linking or vulcanizing happening with the resin. A resin change to a resin made for such parts would make your life easier. I imagine it’s Santoprene resin. A Pibiflex or Kraiburg resin would run/look much better.
