DCS just doesn't want to start in VR : XRresult

[Mac D]

DCS World (latest version) just doesn't want to start in VR.
Yesterday I've updated the Nvida driver (removed with DDU) because of a new GPU (RTX 5090)
Reinstalled DCS World yesterday (after buying the Cold War Map, something with the SSD that it was one not having enought space
Just updated Pimax Play tot the latest version.

Yet I'm constantly getting this error :
2025-04-20 14:45:22.479 ERROR   VISUALIZER (Main): OpenXR failure XrResult failure [XR_ERROR_RUNTIME_UNAVAILABLE]
    Origin: xrEnumerateInstanceExtensionProperties(nullptr, 0, &instanceExtensionCount, nullptr)
    Source: Projects\Visualizer\Source\OpenXR\openxr_program.cpp:225
2025-04-20 14:45:22.479 ERROR   VISUALIZER (Main): OpenXR exception: XrResult failure [XR_ERROR_RUNTIME_UNAVAILABLE]
    Origin: xrEnumerateInstanceExtensionProperties(nullptr, 0, &instanceExtensionCount, nullptr)
    Source: Projects\Visualizer\Source\OpenXR\openxr_program.cpp:225

I've only got Pimax Play installed and the latest OpenXR toolkit (I like to see what the GPU is doing when it comes to frame times and FPS)
No SteamVR, no PimaxXR and the latest OPenXr toolkit :  there isn't anything that should be able to interver with OpenXR.

Removed al mods : still no go.

If anyone knows what's going on here and would be so kind to tell me, it would be very much appreciated

This error occurs when you do not have an active OpenXR runtime. Make sure in Pimax Play you click "Set as Runtime", this should do it.

 

Also, remove OpenXR Toolkit until you get this working without it. 

 

If neither work, search "vcredist" on google and download and install the latest version of that.
