Take care of your team, so you can get back on track
The dynamics of a team is a subtle alchemy, which cannot be imposed but can be worked on.
You could consider the following avenues:
What if you took some time to (re)share everyone's motivations, talents, needs, for the project?
What if your team was a little too... a little too what? What do you want for your team?
What if you invented rituals, signs of recognition, recreational games, gymnastic exercises, language elements... specific to your team?
