I have a custom post type article and custom fields article_keywords which I have created using the ACF plugin https://www.advancedcustomfields.com/, as there were many articles present we were trying to upload the articles through CSV. As all the contents were present in simplified chinese , many posts custom fields were not able to update. We have convert the CSV file from the Microsoft Excel and google sheet as well. Only some of the contents we were able to update.

I am trying to develop a custom plugin in WordPress that requires uploading an audio or video file to the uploads folder. However, I cannot get this part of the plugin to work. I have read several tutorials and replicated the code exactly. It works perfectly for them, but not me. I removed all of my code except for a simple file input to test it, but no luck.
