Not able to use my reverb g2 in VR

Hello,
I have a problem in VR.
At fist, I only tried with open xr (steam vr was not installed) and I was not able to use my reverb : if I used ctrl+tab, my headset stayed black.

I tried to install steam vr, at first no difference, but if I go in steam vr parameters, open xr, and select steam VR for my environment of execution, my game work in VR, but I have very bad performance, only 20 fps, and I can’t move my head in translation, only rotate it, that is strange (my specs : rtx 3080, i7 12700 KF, 64 gb ram).
Any idea of what can be wrong ?
Thanks

Are you starting the g2 before the simulator?

I don’t know if it’s related, but I’ve been having problems with my Quest 3 in the sim over the last couple of weeks.

A friend told me the solution : need to select safe mode on open xr tool kit, and it is OK
