### Godot version

4.0 Beta 11

### System information

Windows 10 version 22H2, GeForce Game Ready Driver Version 528.02, GTX 1070

Since Beta 11 this error is given whenever a project is run in the forward+ renderer with OpenXR enabled. This error is not present with Beta 10 and previous versions.

I've tested with projects created in previous versions as well as the current version (Beta 11)

### Steps to reproduce

Create project, enable OpenXR in project settings, and run.
