2D Unity Platformer Glitch Fix

I'm experiencing environment issues with my 2D Unity platformer. The game is crashing during gameplay due to level glitches. Specifically, players and objects are not colliding properly, leading to unexpected behavior and crashes.

Ideal candidate should have:
- Strong experience with Unity, particularly in 2D platformer development
- Excellent problem-solving skills to identify and fix these glitches
- Ability to optimize game performance to prevent future issues
