Luke Falling Through Map on Pillio

I went back to play the single player mode on PS4 pro and the game seems to stutter and freeze at points that makes the game unplayable ! it's mostly when character audio is playing funny thing is i've played through the game before and had no such problem ! the problem started after i had the luke falling though floor on Pillio level then i reloaded game and it got worse around the Bespin level ! please fix this problem asap.
