@kborowinski thanks! I can reproduce this on 7.5, and wait-debugger works fine in a console so it's not a PS issue nor a preview issue.

Also FYI your logs were ran at info debug level so there's not a lot there, be sure to switch it to debug or trace in the future.

@JustinGrote I did have the debug set to trace. I've run the script again but the logs don't look much different:

StartEditorServices-21352.log PowerShell Trace LSP.log PowerShell.log

Is it another bug? The troubleshooting docs state that after enabling "powershell.trace.server":"verbose" I should select "PowerShell Editor Services Client" in the output pane, but there is only "PowerShell: Trace LSP" log and it contains [info] only:

And trace is sent to the terminal window instead:
