Can you share the full path to Microsoft.VisualStudio.Code.ServiceController.exe, The path should be something similar to c:\Users\whatever\scoop\apps\vscode\1.99.2\data\extensions\ms-dotnettools.csdevkit-1.18.23-win32-x64\components\vs-green-server\platforms\win32-x64\node_modules\@microsoft\visualstudio-controller.win32-x64/Microsoft.VisualStudio.Code.ServiceController <arguments>".

From the log you shared above, it's the duplication of bug #1910 which caused by windows path length limitation.
