Teams don't break loudly. They go quiet first.

Teams rarely fall apart in a dramatic moment. The first sign is quiet. A designer who used to push back stops offering ideas. The meetings get more agreeable and less alive.

It's easy to read that quiet as things going smoothly. Usually it's the opposite. Someone has decided it's not worth the effort to be heard, and that decision shows up as silence long before it shows up as a resignation letter.

The loudest warning a team gives you is the one you can't hear.

Notice the quiet early. By the time a good person is formally checked out, you're months past the moment you could have fixed it.
