Hey Johan, what's the value of "powershell.powerShellExePath" in your user settings? Try clearing it out if it's set to the c:\WINDOWS\Sysnative path.

[johlju]

I had two settings in the User settings. Removed them both and PowerShell Integration Console starts again.
I didn't even thought of looking there, could you add that to the log output maybe?

    "terminal.integrated.shell.windows": "C:\\WINDOWS\\Sysnative\\WindowsPowerShell\\v1.0\\powershell.exe",
    "powershell.powerShellExePath": "C:\\WINDOWS\\Sysnative\\WindowsPowerShell\\v1.0\\powershell.exe"
