"Object reference not set to an instance of an object"

[HomeStarRunnerTron]

Thank you so much for creating this incredible program! So-- to preface, I've never tried using Unity before today. I found this when trying to find something that could record motion tracking data of the headset + controllers to use in, like, Blender or some such. For animation purposes. I'm assuming that once it's all linked up, there's a possible way to nab that information for that kind of use, but maybe I'm totally mistaken. All of this is brand-new to me.

So the stuff I did was:

• Open up the entire Oculus-Linkintosh master folder as a project in Unity
• Build and run the project w/ Android as my platform, and my Oculus Quest 2 selected under Run Device. It boots up, and I see the standard Unity void. My controllers don't show up in the void until I press a menu button.
• I use the same Oculus-Linkintosh folder for the Client steps, because when I tried to copy Scripts/Client and Scripts/Models into a different project, it said the project became corrupted.
• I create an object-- just a Cube. Then I attach LTClient & LTDeviceSimulator to it.
• I drag the LTDeviceSimulator panel into the Simulator value in the LTClient panel. Not sure if that's what meant by "setup the reference".
• I type in what I THINK is my headset local address-- the IP address found in my Oculus' Wi-Fi settings.

• Then, I try to hit run, and I get this error.

NullReferenceException: Object reference not set to an instance of an object

I'm probably doing a million things wrong-- thank you in advance for reading this. All the best!
