Your db will prevent you from deleting records which have foreign relations. I believe the truncate method deletes them as well? But it’s only a guess without actually seeing how you structured your db..

Did you check the output of the call to $project->delete()?

@alen i can delegte just the image here is it

    {
        if(\Auth::user()->can('delete project'))
        {
            if(!empty($project->image))
            {
                Utility::checkFileExistsnDelete([$project->project_image]);
            }
            $project->delete();
            return redirect()->back()->with('success', __('Project Successfully Deleted.'));
        }
        else
        {
            return redirect()->back()->with('error', __('Permission Denied.'));
        }
    }

This will be your code

{ if(\Auth::user()->can('delete project')) { if(!empty($project->image)) { Utility::checkFileExistsnDelete([$project->project_image]);

        $project->delete();
        return redirect()->back()->with('success', __('Project Successfully Deleted.'));
        }

    else
    {
        return redirect()->back()->with('error', __('Permission Denied.'));
    }
}
