always crashing in labyrinth last reward room cannot gain ascendancy points

always crashing in last reward room last lab after walking a bit at the same time and place , no opening chests, no dashing, just walking past the chests trying to touch ascendancy but the game just freezes and disappears. it happened 2 or 3 times already, happened before in first lab but then worked second time now last lab just always freezes and crashes at last room.

edit/update from the other thread

try this and let me know
remove unbind any skill on left click
disable all auras , disable/remove any skills
unsommon/ remove gem for minions
dont use movement or any other skill while walking.
complete chitus plum quest or any other act quest you may have skipped

another thread mentioned packcheck.exe but that executable was not present in the game folder. i copied it from an older instalation and run it it said all files in sync.

edit/update: i took a 2 day break from the game then followed the solutions given by chuter in this thread

as well as the above steps i removed all gear and gems and set item filter to none after last izaro room cleared then entered the reward room and didnt skip the chests i oopened them then was able to walk to the ascendancy stone it worked. not to mention the layout of lab has changed. the game does feel smoother after the steps by chuter, though we will never know where the problem was.
