Steps to reproduce

Randomly happens in VSCode PowerShell terminal. Believe it started with the latest update. Note I do not have to be executing code for this to happen. In this case I left for lunch and when I came back the error was on my screen.

Expected behavior

No error.

Actual behavior

Error.

Thanks @mwilsonin ! Are you using the VSCode PowerShell Extension and if so what version are you using? cc @andschwa

Hey @mwilsonin can you please try the latest preview of the extension? There was a regression around idle handlers, which some versions of the Azure PowerShell module use, that can cause this, but we fixed that and the fix is available in preview.

[mwilsonin]

I switched to the preview version. I will post an update after I've used enough to see whether the problem reoccurs. Thank you.

[mwilsonin]

I have not seen the error since switching to the preview version of the VSCode PowerShell extension. I left my terminal up all night. Normally the error would have occurred after maybe an hour or so, but it was clean this morning. Thank you.

[andyleejordan]

Fantastic, thank you for confirming! We're planning to roll the preview into a stable release this week.
