THE WITCHER BUG WITH RASPBERRY (The Witcher)

please help, in chapter 4 I went through all the quests except for the quest with noon. when the artisan repaired the broken mirror, I go to the raspberry and the raspberry begins the cast price where the guy kills the girl and she turns into noon and after that the black screen is endless, ALTHOUGH I ALREADY SAW THIS CAST PRICE IT WAS AT THE VERY BEGINNING OF THE QUEST. I tried several times to approach the raspberry but it still started this scene and then a black screen. I tried to check the integrity of the files in gog, it did not help, please tell me what to do? it will be a shame to roll back the saves to this quest, because I went through a lot of other quests and didn’t want to go through again
