System Information
Operating system: Windows-10-10.0.18363-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1650 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.77

Blender Version
Broken: version: 3.3.0 Alpha, branch: master, commit date: 2022-05-16 18:20, hash: 8c4bd02b06
Worked: (newest version of Blender that worked as expected)

Short description of error
As you see on image, the adjusted big Empty_suspension_2 on left is linked with Copy rotations as small Empty_suspension_1 on right (we see this on collection duplicated on left), and if Empty_suspension_1 is rotated to reach reaction on Empty_suspension_2 then Empty_suspension_2 is not rotated as empty but collection it is. By this I think is bug.

Exact steps for others to reproduce the error

There is a strangeness. But not in this.
In your example, the Empty does not rotate due to the fact that this requires a parent in whose space there will be rotation.
But why do instances changes?

*My mistake, the rotation is inherited from the original.

Right now your instance is rotating because you're rotating what it's made of.
Your instance parent is not rotating because there is no parent required by the constraints settings

How no parent?
The parent for Empty_suspension_2 is Empty_suspension_1 as on image.
Regarding discus on blender artist I changed organization of files to link this constraints between empty's due direct connection to collection not working.
Also pleas provide the example with prof that Empty_suspension_1 rotating Empty_suspension_2 by Copy rotations constraints.
I made other example and working on pure object but not if collection is connected.

I meant it.

You need the object's parent. You attached an instance to a parent and made a constraint on the parent.

Resolved. The issue was related with bad practice as working in not collections origins to control wheels but elements that was in instance in collection that doing problems and misunderstanding.
