Steps to Reproduce

Consider a very simple script like

Get-ChildItem -Path 'c:' | ForEach-Object {
$f = $_.FullName
$f
}

1. Put a breakpoint on line 2 ($f = $_.FullName) and hit F5.
2. The breakpoint is reached.
3. Hit the Step Over (F10) - debugger hangs. the same is with F5

Hi,

Can you reproduce this using PowerShell Core? I cannot. About to try with Windows PowerShell.

[andyleejordan]

Also @olegk25 could you please provide more logging and environment information by following these steps? Specifically please turn on diagnostic logging. It's helpful to see where it failed, but I want to know what it was doing as it got to that point.

[olegk25]

Hello @andschwa , I've found a workaround by removing (disabling did not help) all other extensions. Now I'll be adding them back and see if I can reproduce the issue again. And thank you for the diagnostics tip :)

[andyleejordan]

Hey that's interesting...let me know which one you find that causes the issue!

[olegk25]

well, no luck catching it again so far... Maybe it was something else. Closing the ticket as non-reproducible

[andyleejordan]

There's a new version of the preview extension out today too!
