Hi, I am doing a project on Hololens 2 using Hololens Remoting Player. With the Microsoft UXT sample project, if an HMD is not connected and I play in VR Preview, the editor falls back to a regular standalone window; meaning it plays in PC mode. But with my project if I play in VR Preview, it just hitches, spits out the ensure message, and nothing happens
