OnTriggerEnter no longer works

It’s not a problem with missing collider or rigidbody. Same code same settings on objects, one box with rigidbody and collider that’s a trigger and player walking into it with collider (no trigger or rigidbody), same layer just to be sure but it makes no difference. I made a demo few months back with that simple setup works just fine, but now in my new project it no longer works. OnTriggerStay, OnCollisionEnter and OnCollisionStay don’t register ether I have no idea why.

I’ve tried messing with script execution order, no luck there, maybe worth mentioning that i have lot more game objects and scripts in current project.

Anyone have any idea what might be the problem?

just this won’t work:

void OnTriggerEnter(Collider col) {
            Debug.Log("It just works");

Edit: To clarify I don’t use collisions or rigidbodies anywhere else.

I figured it out, I disabled Auto Simulation and Auto Sync Transforms in Project Settings → Physics. Check those back on if you have the same problem.
