研究方向

The stack trace points to Microsoft.PowerShell.PSConsoleReadLine.ReadKey and InputLoop; begin there and compare the key, history-navigation, and tab-completion sequence in the report. Reproduce it in the VSCode PowerShell terminal using the listed versions and steps; it is done when the sequence no longer throws Queue empty or causes the reported VSCode behavior.

Note: The keys that follow were not repeated / stuck keys but it seems to have key repetitions?

Additional Context: This occurred during normal usage in VSCode. It seems to be related to command history navigation or tab completion. No custom PSReadLine configuration was applied.

Environment data
Inside VSCode terminal:
PS Version: 7.5.0
PS HostName: Visual Studio Code Host
PSReadLine Version: 2.4.0-beta0
PSReadLine EditMode: Windows
OS: 10.0.26100.1 (WinBuild.160101.0800)
BufferWidth: 195
BufferHeight: 11

Windows Terminal with Powershell 7:

PS Version: 7.5.1
PS HostName: ConsoleHost (Windows Terminal)
PSReadLine Version: 2.3.6
PSReadLine EditMode: Windows
OS: 10.0.26100.1 (WinBuild.160101.0800)
BufferWidth: 115
BufferHeight: 65
Steps to reproduce
  • Open VSCode with PowerShell terminal.
  • Run a series of commands involving pip, get-module, and remove-module.
  • Use arrow keys to navigate command history.
  • Observe crash.

Note: this seems to occur when using vscode with normal editor input, the workflow I was using on the day of the exception ran multiple pwsh instances because of pester test execution in the test extension. not sure if this was a contributing factor though.

Expected behavior

No exception, VSCode does not exhibit odd behaviors like starting a debugging session when any key on the keyboard is pressed

Actual behavior

VSCode starts running arbitrary debugging sessions (F5) and at some point the Exception occurs.
