After completing the Build, the Output Directory named "build" could not be found. Your Project Settings offer the opportunity to tailor the Output Directory to your requirements.

You can go to your Project Settings and navigate to the Build section. From there, you can select or create the directory you want to use as your Output Directory. Once you have done that, try rebuilding your project to see if the Output Directory is created and populated with the necessary files. Remember to double-check the directory path to make sure it is correctly configured with the appropriate permissions needed for the build process to write to it.
