FS2024 suddenly doesnt recognize any more my Pimax Crystal Light headset

I only use my Pimax Crystal Light at MSFS 2020 and 2024 and it worked OK until I tried to enter the UI System through the headset, from there I should have touched something related to the room setting as now when it is initialized a warning appears about being out of my safety boundary, and to return or reset it. As I couldnt find an option to reset or disable the room settings ,I tried setting the quick config, and from then I am able to access the desktop so can watch FS at a big flat screen, but the simulator doesnt recognize anymore the headset and so it doesnt enter VR mode.- I really dont mind about the room settings as I only play Flight Simulators.- Is there a way to discard that room configuration, and perhaps return to normality ? Thanks

I discovered that the openxr runtime was switched at settings, so I return it to Pimax open xr and then the headset is again recongnized. But the problem about the safe zone persists, and sometimes the green grid pops in and out while on flying
