Camera blocked diagonally

Hello
I am new to unity and made a 3d game.
I continued a script which has nothing to do with the camera but by restarting the game the camera is “blocked” diagonally, it can only go from top right to bottom left.

I tried :

  • Cancel all changes
  • Close and reopen the Game tab
  • Checked the script that takes care of the camera
  • Checked the camera options

I think I forgot to specify things,
Thanks =)

nobody knows ?

Okay. Can you post a screenshot?
