Game crashing during cutscene in Saland Hills dungeons final boss and not only

I have been playing the same dungeon for 30 minutes 3 times now and each time between fazes of the boss during its cutscene the game crashes and logs me out. This happened before as well earlier in the story. Seems like it is cutscenes that I cannot skip that crashes my game. I have validated the files, updated windows, GPU drivers uninstall and install the game again. Is there any solution to this?
I’m playing on Neria.
My characters name is Panifrajerr

I just reinstalled the windows and the problem still occurs. Pls help, I paid for silver pack and I really enjoy the game
