Steam VR not recognising UE 5.4 VR Preview

I recently upgraded from a Quest 2 to a PSVR2 for my PC and have switched my OpenXR runtime to Steam VR. While in the editor when I launch a project in VR Preview it doesn’t get recognised by Steam VR. I have tried this with a new VR Tempate project. The only way I have been able to make SteamVR recognise the game has been by building the project. Is there any way to fix this or work around it?
