Thanks @PhilMEFL it would be really helpful if you could also attach the logs--instructions for how to do that are here

In addition to the logs, any extra info about where you see this error and how would be useful. The most useful is a screenshot or a gif of the error occurring and the full text of it.

Hi,
While I can't speak for OP, I can say that this is currently happening for me. Just got Visual Studio Code today since PowerShell ISE doesn't support powershell 7 by default.
It happens only when I'm running Visual Studio Code as a standard user. If I run Visual Studio Code with administrative rights, it works fine, which is not ideal.
Also, is your ms-vscode.powershell extension supposed to be a Preview? Because that's what it's set to. You have two 'Preview' powershell extensions of different versions, but no production/non-preview extension. The second one is ms-vscode.powershell-preview.
I tried installing 2020.4.0 of ms-vscode.powershell but still get the "Cannot create process, error code: 740" error

I'll get some logs tomorrow and e-mail those to [email protected] and run procmon on VSC to see what it's getting hung up on.

@BestUsernameEver2 the preview issue is https://github.com/PowerShell/vscode-powershell/issues/2774.

Can you provide a screenshot of the startup issue as you see it in the UI?

[BestUsernameEver2]

@rjmholt Ahh, that solves the preview mystery then, thank you!

For the startup issue, here's what the UI looks like launching powershell, bottom-right of screenshot:

I e-mailed the trace logs over to vscode-powershell just now
I'll see what procmon finds

I'm silly. Powershell 7's exe had 'Run this program as an administrator' checked in the Compatibility tab, but a UAC prompt wasn't coming up when VSC tried using it so I was none the wiser
Unchecked the box, everything's communicating properly now hehe
Happy Friday!
