Unreal doesnt see anylonger connected quest after last night update ?

Yesterday, I still could work and test with my connected quest via link cable inside of Unreal 5.1.1, but today, the headset is no longer usable. 

I am side-linked, and all from a Windows point of view is ok ... but it's unreal how often I restart it .. it doesn't allow me to test and view in VR any longer. What yesterday worked well?

I hope someone will react it is quite important that i go on with my tests .. 

greetings Martn
