Hey! I met a problem with the window Window > Live Capture > Connections. I succeeded to use it several times with Virtual Camera. But after when I wanted to use the Face Capture when I wanted to open this window, I got the loading popup "Application.ExecuvteMenuItem" waiting for minutes and maybe hours, never reaching the end. I tried to restart the project from scratch but nothing. Then I changed the Unity version and it worked. I re-checked the firewall permissions and there were many rules "Unity 2021.1.7f1 - Live Capture"... I guess the checker in Connections window created them and that's why it told me many times to "Configure Firewall" and I clicked on this button everytime. So I deleted these rules and now the window opens. I think the problem was the checker for the firewall permissions. It should ask only once to configure it. Otherwise it will created several rules that make this bug happen. Now I can try the Face Capture! Virtual Camera is awesome by the way!
