PowerShell debugging stability problems

[v-ruizh]

OS: Win 10 and Linux
Build Version: 20210304.27
PowerShell: 7.1.2

Repro Steps:

1. Create a PowerShell project and set a breakpoint in it.
2. Debug this project.
3. Copy the function url and execute "curl ?name=test" in Terminal.

Expect:
The breakpoint is hit.

Actual:
The breakpoint is not hit.

I'm experiencing the same thing. Tried with both HTTP and Timer triggers. Functions run just fine but the execution almost never gets interrupted at breakpoint (it worked only twice out of tens of retries).

OS: Windows 10 (2004)
VSCode: 1.54 and 1.54.1
PowerShell: Windows PowerShell 5.1, PowerShell 7.1

I suspect that it may be related to the same issue that is causing #2656 to occur ( microsoft/vscode#118256).

We've seen a number of PowerShell debugging issues filed lately. It seems they might all have the same root cause: PowerShell/PowerShellEditorServices#1295, see this comment in particular.

I'll use this issue as the main tracker in our repo.

I'm running into the same problem. Plus I'm getting the following error in the Debug Console
