Can't connect to player, unity crashes after hitting Play

[ViktorVR]

I get the following errors in my console when I open the project. I'm using Unity 2019.3.10f1

When I hit the Play button, Unity crashes

This error does not seem to be related to the code of this demo. I am not experienced with Unity, so I do not know for sure why Unity tries to connect to 127.0.0.1 in your case, but it seems to me like you maybe accidentally changed the settings and tried to make the demo run on a mobile device.

This demo can be run only on a computer, so in Unity, go to File > Build Settings… and make sure the project's target platform is "PC, Mac & Linux Standalone". Please let me know if that helped.
