Issue Description

When launching a new VSCode session, the VSCode PowerShell host process has already thrown an exception in the $Error automatic variable, even when the user has not invoked any commands in the Integrated Terminal.

Maybe this is relatable to an issue I had with PSv6 remoting https://github.com/PowerShell/PowerShell/issues/3553

[pcgeek86]

Looks very similar, yes.

Thanks guys! This is strange, I'll take a look. I wonder if I'm causing it somehow.

Just gave this a try and it's not reproing. It's probably that old PowerShell/PowerShell issue. I'm going to close this but if you still see it let me know!
