Game freeze after completing a quest

My game keep freezing after completing a quest. The "change Polikhim Hobo quest status" fix doesn't work, i've already completed that quest long ago.

Edit: that's the exeption

Ok I solved the problem. Using a profile editor i've searched for "started" quests and found one bugged with an unknown trader and a string of code for the name of the quest. The bugged quest was "5d25dae186f77443e55d2f78": "The survivalist path. Zatoichi"
