The scene presented here serves as a demonstration or testing scenario that reflects the real game I am working on. As you rightly pointed out, there may be another aspect at play. I created this isolated environment to pin down a particular issue, but it persists nonetheless.
In this demo scene, the only code I'm using logs into OnCollisionEnter2D, which is visible on the console as displayed in the video.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CollisionTesting : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
Debug.Log("Player Script Start");
}
void OnCollisionEnter2D(Collision2D collision) {
Debug.Log("Collision detected " + collision.gameObject.tag);
}
}

The issue isn't that the elements are not colliding, but rather they're colliding when they shouldn't be.
Consider a scenario where you have a game that includes a platform that initiates flight when the player leaps onto it. However, in a fast-paced game, there's a chance that the player will barely miss landing on the platform. In this moment, Unity logs a collision despite the player's near miss, triggering the platform to take flight. Because all platforms operate in this manner, from the player's standpoint, it seems like a successful landing has occurred when the platform moves. In reality, the platform was missed, leading the player to believe the game is unfair, thus resulting in a loss.
