Connected Body fields are missing from joint components when the PuppetMaster assets are imported

Reproduction steps:

1. Open the “PaidAssetTest” project
2. Open the “NewScene” scene
3. Select “Cube” in the Hierarchy
4. Observe the Configurable Joint component in the Inspector

Expected result: Configurable Joint component has “Connected Body” and “Connected Articulation Body” fields
Actual result: Configurable Joint component doesn’t have “Connected Body” and “Connected Articulation Body” fields

Reproducible with: 2022.1.0a13, 2022.1.20f1, 2022.2.0b12, 2023.1.0a15
Not reproducible with: 2020.3.41f1, 2021.3.12f1, 2022.1.0a12

Reproduced on: Windows 10

Note: there’re reasons to suspect that this behavior is caused by the script or custom inspector, however, I couldn’t determine it since removing most of the scripts causes compilation errors
