Dragon age 2: Mark of an assasin loading problem

Hello,

Recently i decided to replay dragon age 2.

I completed the main game and decided to do the dlc's.

Legacy went well but i have a problem with Mark of an assasin.

Everytime i try to load to the the hunting grounds, the loading screen freezes .

I thought i fixed it  by skiping the hunting grounds with the help of the console, but again when the game is loading to the dungeons , the loading screen becomes infinite.

With the console i have been able to check that only the hunting grounds and the dungeons are locations that the game does not load

and i don't really know how to fix it.
