Hey, i finaly fix the problem!!
so i fix it by deleting some stuff in main file.
you need to cut/paste in a created file on your desktop if the game doesnt work without the deleted files. but that’s work for me so i hope that’s work for you!!!
1: Delete all files in left of the screen in Steam/steamapps/cummon/Conan Exiles/ConanSandBox/content
2: Delete all files in right of the screen in Steam/steamapps/cummon/Conan Exiles/Engine/content
and restart the game
