Crashing randomly

[Nova405]

While trying to play reverse mode just now i jumped onto the elevator pad that would bring me down and game crashed, yesterday i was able to get down it and move through a chamber or two before it crashed, and while playing odyssey mode it randomly crashed right before the area you enter glados's room (after the area where wheatley would do his "magic" to open the wall), i am using a custom portal gun aswell as ReShade (Already tried disabling what i had enabled in ReShade and it didnt change anything)

EDIT: ive been playing more and managed to get to chapter 3, i believe the issue is entering the end elevators too fast
