Laravel import csv file failed

I tried to implement an import csv file on my web. When I tried to import the csv file, the csv file is not saving into the database, and when I tried to dd() it, it shows no errors, and not showing the result of the dd(), but the import failed. How to resolve this issue?

The model :

<?php

namespace ModulesUserImports;

use AppUser;
use CarbonCarbon;
use IlluminateSupportFacadesHash;
use IlluminateSupportFacadesValidator;
use IlluminateSupportFacadesDB;
use MaatwebsiteExcelConcernsToModel;
use MaatwebsiteExcelConcernsWithCalculatedFormulas;
use SpatiePermissionModelsRole;

class VendorImport implements  ToModel, WithCalculatedFormulas
{
    /**
    * @param Collection $collection
    */

    public function model(array $row)
    {
        
        // Implement your import logic here
        //dd($row);
        $user = new User([
            'name' => $row[0],
            'first_name' => $row[1],
            'last_name' => $row[2],
            'email'=> $row[3],
            'email_verified_at'=> Carbon::now()->timestamp,
            'password'=> $row[5],
            'address'=> $row[6],
            'address2'=> $row[7],
            'phone'=> $row[8],
            'phone2'=> $row[9],
            'birthday'=> $row[10],
            'city'=> $row[11],
            'state'=> $row[12],
            'country'=> $row[13],
            'zip_code'=> $row[14],
            'last_login_at'=> $row[15],
            'avatar_id'=> $row[16],
            'bio'=> $row[17],
            'status'=> $row[18],
            'create_user'=> $row[19],
            'update_user'=> $row[20],
            'vendor_commission_amount'=> $row[21],
            'vendor_commission_type'=> $row[22],
            'deleted_at'=> null,
            'remember_token'=> $row[24],
            'created_at'=> Carbon::now()->timestamp,
            'updated_at'=> Carbon::now()->timestamp,
            'payment_gateway'=> $row[27],
            'total_guests'=> $row[28],
            'locale'=> $row[29],
            'business_name'=> $row[30],
            'avatar'=> $row[31],
            'messenger_color'=> $row[32],
            'dark_mode'=> $row[33],
            'active_status'=> $row[34],
            'verify_submit_status'=> $row[35],
            'is_verified'=> $row[36],
            'user_name'=> $row[37],
            'member'=> $row[38],
            'role'=> $row[39],
        ]);
        
        $user->save(); // Corrected method call

        if ($role = Role::findById(1)) {
            $user->syncRoles([$role]);
        }
        return $user;
    }
    
    // public function sheets(): array
    // {
    //     return [
    //         'users' => new UserImportSheet(),
    //     ];
    // }
}

The controller :

public function import(Request $request)
    {
        $this->validate($request, [
            'file' => 'required|mimes:csv'
        ]);
    
        $file = $request->file('file');
        $nama_file = rand() . $file->getClientOriginalName();
        $file->move('file_vendor', $nama_file);
    
        Excel::import(new VendorImport, public_path('/file_vendor/' . $nama_file));
        
        return redirect()->back()->with('success', __('Upload successfully!'));
    }

The route :

Route::get('/import', 'UserController@import_form')->name('user.admin.import.form');
Route::post('/import', 'UserController@import')->name('user.admin.import');

The view :

<form action="{{ route('user.admin.import') }}" method="POST" enctype="multipart/form-data">
    @csrf
    <input type="file" name="file">
    <button type="submit">Upload Excel</button>
</form>
