5D4 camera speed control dial cannot be rotated.

Press the middle lock button.

Some SLR mode dials have a locking key in the middle, which can only be turned after being pressed.

The purpose of this design is to prevent the photographer from inadvertently changing the shooting mode because of careless touch. If it is not because of locking, there may be something wrong with the mode dial.
