ms-vscode.powershell@2025.4.0

Steps to Reproduce

• In C:\Users\<user_name>\Documents\PowerShell\Microsoft.VSCode_profile.ps1

. "C:\Users\<user_name>\Documents\PowerShell\Microsoft.PowerShell_profile.ps1"

• In C:\Users\<user_name>\Documents\PowerShell\Microsoft.PowerShell_profile.ps1

function prompt {
    Write-Host “===” # here has breakpoint
    Write-Host ">" -NoNewline
    return " "
}

• Add breakpoint (like screenshot below)

• FIRST TIME Click Run button on the right corner of VSCode and everything works fine, then click Stop button in the middle of debug panel.

• SECOND TIME Click Run button then click Stop button, this time it takes longer for debug process to stop

• THIRD TIME Click Run button, after sometime error comes connect etimedout. And maybe result in high CPU usage.

any run debug try after that cause the same error unless restart VSCode

not sourcing another .ps1 in Microsoft.VSCode_profile.ps1 and debug, everthing works well.
