How to reproduce:
1. Open the attached “repro-project.zip“ project
2. Build the project
3. Observe the Console

Expected result: The Build is finished.
Actual result: The Build is interrupted and errors are thrown in the Console.

Reproducible with: 2022.2.1f1 (1.0.0-pre.15), 2023.1.0a23 (1.0.0-pre.15)
Could not test with: 2020.3.42f1, 2021.3.15f1 (Entities-Graphics is not supported)

Reproducible on: Windows 10, macOS 11.6.5 (Intel)

Errors:
Shader error in 'Hidden/OcclusionDebugOccluders': 'UnitySetupInstanceID': no matching 1 parameter function at line 62 (on d3d11)
Shader error in 'Hidden/OcclusionDebugOccluders': invalid subscript 'instanceID' at line 62 (on d3d11)

Notes:

• The project uses the occlusion define in Project Settings > Player > Scripting Define Symbols
• The project has the MockHMD package installed

* and enabled in Project Settings > XR Plugin Management > Desktop tab
The project has openGL included in the API list for macOS / Windows in Project Settings > Player > Other Settings

• No repro when:

** The MockHMD package is not installed
* The openGL core is removed from the API list and then the editor restart
Still repros when:
** Project Settings > URP Global Settings > Strip Debug Variants is ON
* occlusion define removed from project settings*
** either option for the render mode dropdown in Project Settings > XR Plugin Management > MockHMD
** Project Settings > XR Plugin Management > Initialise on Startup is OFF
** Or, MockHMD is disabled in the plugin providers list
