Realtime Reflection Probes in HDRP stop working and NullReferenceExceptions are thrown in the Player log when the scene is reloaded



Reproduction steps:
1. Open the attached “IN-55505_HDRP Probe“ project
2. Open the “LaunchScene”
3. Go to File > Build Settings…
4. Make sure the “LaunchScene” is the first one (index 0) in the Scenes In Build pane and the “OutdoorsScene” is the second one (index 1)
5. Click on “Build And Run” (select the folder of your own choosing)
6. In the Player, press the “space” key to load the “OutdoorsScene” (might take a while sometimes)
7. Observe the “Reflection Probe” GameObject producing a very bright white reflection on the “Cube” GameObject
8. Press the “escape” key to unload the “OutdoorsScene”
9. Press the “space” key again to load the “OutdoorsScene” once more

Expected result: There is a very bright white reflection on the “Cube” GameObject (just like after the 7th step)
Actual result: There is no bright white reflection on the “Cube” GameObject and a couple of NullReferenceExceptions are thrown
