Not working properly

This plugin caused a big problem: after installing the new version of PHP 7.4, the widgets of the elementor pro functions didn’t work anymore and I couldn’t modify the pages created with Elementor Pro. After disabling this plugin, everything is fine. I already have the Seninblue newsletter pluggin on my website and woocommerce but this pluggin is a problem so I deactivate it and uninstall it until you update it properly . If you know where the problem comes from please give me the solution.
