Does anybody have any idea what this error means?

NullReferenceException Unity.Engine.GameObject.GetComponentCollider (at C:/buildslave/unity/build/artifacts/generated/common/runtime/UnityEngineGameObjectBindings.gen.cs:38)

My project was working fine then out of nowhere this happens every frame, Does anybody know what this means?

The NullReferenceException means that the GetComponentCollider is failing for some reason. There is likely some condition under which the object you are accessing doesn’t have a collider.

It might be that the object you are trying to access doesn’t have a collider.
Also check if you wrote ‘GetComponentCollider’ instead of ‘GetComponent()’
