Star Wars Castaways performance issues in Apple Arcade

After playing a while with two other players in Star Wars Castaways, it started skipping frames, with slow and jerky motion. Continued playing and the other two players eventually left the game. I got to the end of the level, completing the goals, and just as the cut scene started, the game froze. Had to force quit the game with the Apple controller. Restarted the game and began playing with another player in the game and it worked normally.

This game has similar performance problems a few times a week. Is something wrong with my system, or is the game just this buggy?

I’m using an Apple TV 4k, connected by ethernet to 500mbs Xfinity.
