Ratchet and Clank Future: Tools of Destruction [BCES00052]

I played the game for  for a week or so 32 hours on time played fully completed the game and did not find any game breaking glitches
But the game is unstable(low fps) at some parts like when fighting a specific boss and it has a tendency to crash randomly(freeze the game).
might make a video if more proof is needed.

Using rpcs3-v0.0.11-10617-f1b1c905_win64

Setting I changed are:
Renderer : Vulken
Resolution Scale : 300% (for a sharp looking image)
VSync: enabled (not sure it it helps but seem to stop some crashes)
Multithreaded RSX: enabled (helps a bit in performance but works fine without it)

My specs:
RTX 2080
Ryzen 7 3700X
16GB RAM 3000 MHz
and its on my SSD if that affects anything

this is my first post so tell me if I did anything wrong
