Novigrad does not let in the story (The Witcher 3: Wild Hunt)

Good day to all, gentlemen of the forum! I need your help and advice! Faced the following problem: according to the quest where you need to lure Doo Du with the help of a theatrical performance, there is an extra. the task is to hire a group of jugglers. This is where troubles start for me when I go into the jugglers room, the girl plays the lute, but she does not appear in her hands, and as soon as it comes to dialogue with her, the screen becomes cloudy and a long download begins, which ends with a crash. This is repeated every time. Well, I thought to hell with them with jugglers and did not hire them, I immediately started the play, but as soon as she got to the moment when Geralt invites a security guard to the stage, the game also freezes and always loads. A similar trouble arose with a side task (hunting for a monster, which I took in the same Novigrad).
I must say right away - I play on a bucket of the Jurassic period: percent. Some kind of AMD atlon (2 cores) at 3GHz, video geforce 650ti boots, 8 gigabytes of operatives, the paging file was disabled, but the trab was also with the paging file, all firewood was updated.
If anyone has experienced this please help!
