extensionHost running dozens of pwsh -c "Get-Command -All"

[SOM-Scott]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

There are often well over 15 extensionHost processes running pwsh -c "Get-Command -All" which lags out my system, each one taking 5-10% CPU.

Thanks for your submission!

Do you have the PowerShell Command window enabled? That could be a potential culprit, but there should only ever be one. That particular component is deprecated. I'm unable to reproduce it.
