[Star Wars] Is the reason why Vader stopped Boba from shooting Chewbacca was to protect C3PO?

No. It was to stop collateral damage.

He needed Han alive to test the carbon freeze. He needed Leia alive as a political prisoner. He needed Lando alive because it's easier to deal with Cloud City without the place rioting. And he didn't want the freeze chamber equipment damaged.

He stopped Fett because he might have missed.
