In this link there's a video of them appearing to be frustrated at each other over something in the huddle. I'm guessing it was about defensive rotations as you read through the blunder the Mavs had in Pic N Roll defense.
Josh is a good dude though looks like he later tried to motivate Luka.

If the losses piling up weren’t enough, or the terse postgame quotes didn’t give us a clue, this moment in the third quarter certainly did.
One of the benefits of being unable to watch the Mavericks through a traditional TV provider is that instead of watching commercials, sometimes my feed shows what’s going on in the arena during a stoppage of play. To be fair, this particular moment between Luka Doncic and Josh Richardson isn’t unique, far from it. Moments like this happen across the league, it’s just if you’re not in the arena, you miss it. Still, it paints the picture of a basketball team that’s just not having too much fun right now.
