If your 2D Unity game character suddenly stops as if hitting an invisible object, the issue may be collider-related. For instance, your character's collider might be interacting with small gaps or unintended colliders in your level design. Check for overlapping or misaligned colliders and adjust the physics layers.

Another possibility is a script bug causing velocity to reset unexpectedly. If you're implementing mechanics like in Brawl Stars, ensure your dash or movement scripts don’t accidentally stop momentum. We have faced same issues in this game due scrips conflict.

Optimize your Rigidbody2D settings—like friction or collision detection—to prevent unwanted behavior. Debugging the scene view while testing can help identify hidden obstacles.
