In Android x86_64 build, all characters (including players) have abnormal movements.

After testing, we found this issue with packages on the x86_64 architecture. Packages on arm64-v8a don't have this problem.
When you enter the world and summon mobs, you can see that all entities—including players, mobs (zombie villagers, endermen, pigs, horses, villagers), and even the player character—exhibit severely abnormal movements. Specifically:

No animations​ are present for any actions (e.g., walking, attacking, riding, idling).

Entities instead move via mechanical translation​ (jerky, animation-less "sliding" or "teleporting" across the screen), lacking natural motion cues.
