Intellisense Hanging in Editor

[GHartsfield]

Issue Type: Bug

As of today when I updated to 2020.3.1 there have been frequent intellisense hangs/crashes. I cannot seem to find a way to reproduce it reliably but it happens within a few minutes of reloading either the extension or vscode. Had been working consistently for about a week on the same project in the previous extension version with no issues. No other changes to the environment. Attached the error logs and editor services verbose output.

Extension version: 2020.3.1
VS Code version: Code 1.43.2 (0ba0ca52957102ca3527cf479571617f0de6ed50, 2020-03-24T07:38:38.248Z)
OS version: Windows_NT x64 10.0.18363

Thanks for the info! Can you please set the log level to Diagnostic and try to repro again? It looks like the log files in the zip are basically empty... I expected to see more if they were proper logs. This might be an indication that the issue could be elsewhere but we need to know more.

"powershell.developer.editorServicesLogLevel": "Diagnostic"

Thanks for the reply, I thought there wasn't much in the logs as well - unfortunately those were taken in diagnostic mode. I have switched back over to the non-preview extension and the problem has gone away. Don't know if its relevant but I am using custom prefixes in the modules which your GetCommandSynopsisAsync refactor seemed to fix - now that I'm back in non-preview I have no intellisense issues but I do have issues with the module prefixes again.

My intellisense doesn't work at all with the latest preview 2020.3.1, anywhere in my code base. I have dropped back to 2020.3.0 where it appears to work reasonably well.

@stevenebutler @GHartsfield I just published 2020.3.2 of PowerShell Preview. Can you give it a try and let me know how works for you? Thanks!

This is fixed in PowerShell/PowerShellEditorServices#1248
