图片上传错误“创建对象时发生类型错误” Magento 2.4.1

如何解决图片上传错误“创建对象时发生类型错误” Magento 2.4.1

在我的自定义表单中，我有一个选项图片上传。没有图片上传表单提交没有任何错误。但是当我使用图片上传代码并提交我的表单时出现错误

创建对象时发生类型错误： MKF\CustomApplication\Controller\Index\Submit\Interceptor，参数 4 传递给 MKF\CustomApplication\Controller\Index\Submit::__construct() 必须实现接口 Magento\Framework\ObjectManagerInterface， 给定的 Magento\MediaStorage\Model\File\UploaderFactory 实例， 叫进来 C:\xampp\htdocs\magento_new\generated\code\MKF\CustomApplication\Controller\Index\Submit\Interceptor.PHP 第 14 行
