@Robertofilho,
Do other commands work for you? Like calculator and notepad?
Does that start netflix: command and your turn off PC command work if you run them from a cmd prompt?
I upgraded my PC to Windows 11 and it's working for me.
The first time I logged in after the upgrade, the Windows firewall prompted me to ask whether I want to allow node to access the internet. I allowed it because it's part of the TRIGGERcmd agent. I wonder if prompted you and you didn't allow it?
