Poor Framerate on Updated Treasure Cove

I don’t know why this is an issue, as other levels do not have this, but since the Minigolf level Treasure Cove updated, this course has been unbelievable laggy with the frame rates!
I never had such an issue before in this game except for this level.

Why is the Framerate having so much issues and how can I fix this?
