Verified on the latest build 20240611.3, it doesn't reproduce for now. So close it.

This issue still reproduces on App Service extension build 20240726.1, reopen it.

It seems like the preDebug task, dotnet clean, isn't finishing. Maybe it's a timing issue? Or is the dotnet clean task failing somehow?
