MU Plugin that changes upload path has stopped working

Hello,

I had a code that you helped me insert using mu-plugins to change the upload path of uploaded attachments that worked fine up until 2022. You can find the topic here:

https://ww.wp.xz.cn/support/topic/change-dir-of-uploaded-files/

We checked yesterday and saw that all attachments are going to the default uploads folder of WordPress now and we would like -if you can ofcourse- to know what has changed during updates and has stopped working and how can we update the code to work once again.

The code we have now is this one:

<?php
/**
* Plugin Name: Forminator - Change Upload Path
* Plugin URI: https://premium.wpmudev.org/
* Description: mu-plugin for changing the Forminator upload dir to /uploads/forminator/submission_id.
* We also had an another git to custom the upload path to wp-content/forminator/form_id/YYYY/MM/DD/submission_id
* which you can check here: https://gist.github.com/wpmudev-sls/639f2b6d711016e74ffa86d3a8e3c0d3
* Version: 1.0.0
* Author: Konstantinos Xenos & Thobui @ WPMUDEV
* Author URI: https://premium.wpmudev.org/
