Project validation spam errors in the console when no main camera

[anonymous2585]

Hi,

I just updated to Unity 2023.2.12f1, so OpenXR updated automatically to 1.10.0. I manually updated the microsoft OpenXR plugin to 1.10.0.

In our application, there is a root scene that load sub-root scene depending on the plateform. The main camera is in the sub-root scene, so most of the time, I don't have a main camera open in the editor.

When opening the OpenXR Project Validation, it spam this error, because there is no main camera:
