Firstly, what caused your game freeze? Did you patch your game while being in this area while having an older game version patch?

yes i think so 

and i don't know to fix this and i want not retart the game i do an nuzlocke run

That's the issue then, if you still have the older game version, walk your way back to a pokemon center nearby or Oblitus city since that map wasn't remade, and save your game there, then play again on the new patched version.
Other than that, if I manage to fix your game, you'll miss on new game events that was place in the game "since I have to go throw them myself to save your game a new"
