Vr preview mode is disabled

Hi, the VR preview option is disabled, I am using Unreal Engine 5.2 and open xr plugin, which started a few weeks ago when I was trying to connect to Quest 2 to my PC. It connected I connected with the cable, and I can share the APK file from PC to Quest 2 but the VR preview is disabled, it's showing an error [ Oculus is not set as default openxr runtime. This might prevent some applications from launching correctly. Set as default ] When this error started to come from then vr preview option is disabled.
