The issue is related to the failure of the build command due to the presence of a space in the path to the Python executable (C:\Program Files\Python39\python.exe). This results in the command being misinterpreted, leading to a failure in executing the build process. This is a common issue in command-line environments where paths with spaces are not properly quoted or escaped.
