I don't know why it gives me this error. I tried to deal with it a lot, but it gives me this strange error. I made another file and put exactly the same things in it and it worked, but I need to add it to this project

PDF不存在于app/Models文件夹中。尝试以下操作：
```php
use App\Models\PDF; // 替换为"use PDF"（通过别名调用）或"use Mccarlosen\LaravelMpdf\Facades\LaravelMpdf as PDF"（直接调用）
英文:
PDF doesn't exist in app/Models folder. Try this:
use App\Models\PDF; // replace this with "use PDF" (for calling via alias) OR "use Mccarlosen\LaravelMpdf\Facades\LaravelMpdf as PDF" (for direct calling)
