Flutter : Can't launch project though it worked perfectly a few minutes ago

Question

So I was working on a flutter project and everything was fine, it ran perfectly on my device but there was a shortage and my computer rebooted, since then the project won't run.

Here's the error message:

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:packageDebug'.

  A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade java.io.FileNotFoundException: C:\Users\Amane Hosanna\Desktop_\FLUTTER\complete guide\budgetizer\build\app\intermediates\signing_config\debug\out\signing-config.json (Acces Denied)

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Go to the CLI of this project and run: flutter clean
