Joint physics is broken when in Play Mode

Unity: PhysX

As Designed

2021.3.X

It seems that the Configurable Joint connectedAchors are not set up in the problematic scene. If the autoConfigureConnectedAnchor property is set to true on the problematic joints, the scene starts to behave normally.

Reproduction steps:

Open the user’s uploaded project in Google Drive ("Bridge-Legends.zip")
Open the "Assets/Content/Scenes/Metagame.unity" Scene
Switch to the Android platform
Enter Play Mode
Play level 1

Expected result: The bridge does not break and the level can be passed
Actual result: The bridge breaks

Reproducible with: 2021.3.13f1, 2022.1.22f1, 2022.2.0b15, 2023.1.0a17
Could not test with: 2020.3.41f1 (BakingCamera.cs(19,35): error CS0234: The type or namespace name 'PrefabStageUtility' does not exist in the namespace 'UnityEditor.SceneManagement')

Reproduced on: Windows 10 Enterprise 21H2

Notes:

The user stated that after upgrading the Editor version from 2020 to 2021 joints no longer work as expected
The problem persists only in the Editor. The build for Android devices works fine
