In Play Mode, an extra Sync Call is made every frame when a GameObject has a Rigidbody 2D component

How to reproduce:

1. Open the “Repro.zip“ project
2. Open the “New Scene“
3. Select the “Physics (2D)“ performance counter
4. Enter the Play Mode
5. Observe the “Sync Calls“ attribute in the Profiler Window

Expected results: 1 Sync Call is made every few frames and every other frame 0 Sync Calls are made
Actual results: 2 Sync Calls are made every few frames and every other frame 1 Sync Call is made

Reproducible in: 2022.3.15f1, 2023.2.4f1, 2023.3.0a18
Couldn’t test in: 2021.3.33f1 (no “Sync Calls“ attribute in Profiler)

Reproduced on: Windows 11 Pro
Not reproduced on: No other environment tested

Note: Sync Calls should be called every Fixed Update frame and not every frame
