Steps to reproduce

  1. Open a dotnet porject with a regular account(non admin privilege)
  2. Press F5 to start debugging the project
  3. Wait a while to building process
  4. See error on output window

Expected behavior

Start a debug session

Actual behavior

On integrated terminal the process finishes without error but application don't start, as if I only asked to build the app

Additional context

Running vscode with admin privilege the problema do not happen. I tried using only C# extension and also with C# Dev Kit, both last available version and also with versions from 6 months ago. None of those options has worked without admin privilege.
I unistalled vscode and installed again, I tried installing per user and system wide and nothing made it work.

It happens even with a dummy console application just created by dotnet CLI.
