Integrated Console Hangs On Load

Issue Description

I recently upgraded from v2020.4.3 to v2020.6.0 and the console no longer loads at launch it just hangs.

Steps taken

1. If I revert the back to v2020.4.3 the issue goes away.
2. I have tried completely removing extension and reinstalling,
3. I have tried disabling this version and installing the preview version v2020.9.0, results in the same hanging behaviour but it does produce this exception.

likely unrelated but @Garfius PowerShell Core 6 is EOL. You’ll want to upgrade to PowerShell 7. PS7 does have a better experience in the extension so it’s worth switching too… (assuming it can start 😅 )

YES!

Solution: yum update powershell

Thank you very much.

My apologies for posting before trying to update.

@Garfius please try out the current PowerShell Preview extension and see if you get an error stack trace
