Stack Overflows in Specific File

[functionkey-12]

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

While in a specific Workspace, my PowerShell Extension experiences a stack overflow. This occurs while I am typing in the editor. It has happened after typing 1 character in the active file. If I restart the extension, and only work in the console, it does not crash.

The workspaces settings file is just a directory location, and the cwd for the extension. I have remove the values from these keys and the issue persists.

PowerShell Version

ms-vscode.powershell@2023.8.0

Steps to Reproduce

I restarted the extension and in the editor window, I start typing. Sometimes I am able to type out a line, sometimes I am only able to type "$".

Visuals

Moments before this screenshot I restarted the extension, and typed the single "$" in the if statement. I have removed any configuration from the workspace file.

Logs

I have attempted to capture the output to the terminal, as shown in the screenshot. This text is quickly cleared as the extension halts. There maybe more output, but I am unsure.

PS 7.3.8> Stack overflow.

I have been unable to work on the script due to the overflows as they occur after a few character inputs, so I pulled the contents and created a new window. Once the contents had been pasted, I attempted to continue working on the script and the overflow started shortly after.

Can you share the file that this is happening with?

This issue resolved itself after a VSCode update to 1.84.
