OpenXR in UE5 - Activating '-XRtrackingonly' in UE 5.4 crashes the editor when launching NDisplay

OpenXR
1

Ever since they deprecated and removed SteamVR plugin, I’d seen on youtube, reddit, and Unreal Engine Forums that now you have to create a shortcut for the engine with the command-line argument “-XRtrackingonly” and activating OpenXR and the OpenXR Vive Tracker Plugins if you want to continue using the Vive Trackers for Virtual Production.

I tried it and the tracking works perfect in the editor, but when I hit the “NDisplay Launch” (with the plugin: NDisplay Launch) button the editor disappears completely.

On Switchboard, I can’t do real time editing while NDisplay is active because the editor also disappears when doing the same thing in there.

Has anyone found a solution for this or have another way to use NDisplay with Vive Trackers with no issues in UE 5.4?

This seems rather specific to Unreal Engine, if you haven’t tried already I’d suspect you have better luck getting help on their forums.
Switchboard has a setting that minimizes all windows when it launches an nDisplay application - is that what you mean with “the editor disappears”? If so, there is a setting in Switchboard in the section “nDisplay Settings” called “Minimize Before Launch”, have you tried unchecking that?
