How to reproduce:
1. Extract and open the attached “IN-132815.zip“ project
2. Open the Assets/Scene/SampleScene.unity scene
3. Open the Project’s solution in Rider
4. In Rider Navigate to the Assets folder
5. Open the “Example.cs” Script
6. Click on the “Unity” logo looking icon and select “Attach to Unity Editor“
7. Create a breakpoint at line 15: “if (targetCollider != null“
8. Navigate back to the Unity Editor
9. Enter Play mode and wait for the breakpoint to activate
10. Once the focus switches back to Rider, try to expand and otherwise inspect the “targetCollider” variable
11. Observe the crash
