UE5.4 city sample shader error (bug)

I downloaded the City Sample project for UE5.4, I have broken materials of cars and people, shift collisions to the hootic sides, I could not find a solution to the problem on the forom
Here are the steps I used to try to fix it:

  • deleting the shader cache folder, I thought there was a shader mishandling (didn’t solve the problem)
  • updating the video driver and reinstalling it cleanly (didn’t solve the problem)
  • completely deleting the project and downloading it again, I thought maybe some files just downloaded incorrectly or were broken (didn’t solve the problem).
  • reinstalling game engine and Houdini plugin (did not solve the problem)
    I am writing here in the hope to find help in solving this problem
