Unity crash almost always in the same zones

it’s been a few weeks now I had very often crashes (not 100% of the time but very very frequently) in the same zone always.
For example : unity crash in Act 9 in the Temple rooftop area
The same happen in the cemeteries, and tonight I had 5 crash in a row the Sepulchre of the lost zone.
The default in windows event is either UnityPlayer.dll or GameAssembly.dll.

Everything is up to date from my side, and I repaired the files also.

It’s very annoying because at least I managed to go through act 9 finally, and then everything was a breeze, until I arrived in some cemeteries or even worst Sepulchre, now I simply can’t go further.
