“RenderSettings customReflection texture has invalid type” error keeps getting thrown even when Environment Reflections was set back to Skybox from Custom with an invalid texture

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Open the Lighting window (Window > Rendering > Lighting)
3. Open the Environment tab in the Lighting window
4. Change the Source property to "Custom" under the Environment Reflections
5. Select any of the default 2D textures
6. Change the Source property back to "Skybox" under the Environment Reflections
7. Enable/Disable Fog a few times under the Other Settings
8. Observe the Console window

Actual results: “RenderSettings customReflection texture has invalid type” is thrown every time Fog is enabled/disabled even when the Environment Reflections Source is already switched back to Skybox and the Custom property should not matter any more as it's not being used

Expected results: No errors are thrown

Reproducible with versions: 6000.0.60f1, 6000.2.8f1, 6000.3.0b6, 6000.4.0a2

Tested on (OS): MacOS Silicon Sequoia 15.6.1

Notes:

• Restarting the Editor does not fix the issue, the error is being thrown instantly once the Project/Editor is loaded
