How to Troubleshoot Collision Detection Issues in my Game

I have a question regarding the game I’m developing. Within the game, there’s an action where a specific player triggers an event upon colliding with another player, resulting in the activation of a visual effect (VFX) and a sound effect (SFX). When testing in the Unity editor with multiple virtual players, everything works smoothly. However, upon loading the game and testing it on the platform, the collisions are not being detected, causing the functionality that works in the editor to fail. Does anyone happen to know why this might be occurring? Thank you very much.
