S24 Nebula blank screen right side, drak on left side

Just bought Xreal AIR, to run with my new S24 Ultra which is absolutely compatible. It works in Dex mode, and when Nebula starts,
switch mode
i see blank light on right glass and left glass is dark
i tested it with my Fold 2 and glass works fine.
then all is frozen, i must unplug, close Nebula manually, restarted phone, same problem.
seems a Nebula problem on S24?
Any help or advice is appreciated
