Meta XR Simulator Synthetic Environment Server rooms are missing

Hi im pretty new to Unity development with the Meta XR SDK. Im on Unity 6.2 and using Meta All-in-One SDK version 78. I've been trying to figure out how to launch a Synthetic Environment Server on the Meta XR Simulator and everytime I try to enter play mode using the Simulator and launch a room from the list of rooms, Unity fails to find the .exe file in the directory path above. And sometimes the editor would just crash when I press play. 

 

I tried removing and reinstalling the packages but it just won't work. Any solutions or am I missing something? Thanks

    Hello there!

    Did you add the Synthetic Environment Samples through the Unity Package Manager? Below I linked our document on exploring the SES with sample scenes.

    Have you been able to properly open the SES window, and made sure to have the SES window open while you attempt to launch the sample scenes? Any additional information you can provide helps me to resolve your issue!

    Looking forward to hearing back from you!

    Hi, thank you for the reply. No, I haven't added the SE samples from UPM. I tried opening the samples package link shown in the page you mentioned but it says that it is no longer available. For context, I installed the Meta XR Simulator package as a dependancy through downloading the Meta All-in-One SDK. 

    Below is a screenshot of when I try to launch one of the rooms. Is this the correct SES window you mentioned? Thanks!
