How to reproduce:
1. Create new HDRP project
2. In Hierarchy search bar enter "camera"
3. Select the only active object
4. Leave Editor running

Expected result: No errors in Console and Scene is still rendered
Actual result: Multiple errors thrown in Console and Scene is no longer rendered (turns gray)

Errors:
