Hi, Our Elementor Header and Footer builder features is a part of Elementor Pro.
If you are using our Pro features on your website, you’ll need to open a support ticket at my.elementor.com.
WordPress.org rules state that commercial products are not supported here.
Otherwise, our Hello theme comes with a header and footer customization feature in the Appearance tab.

I am actually using Elementor free on this website. I just made a template block for footer.
Sorry for not noticing it earlier, seems like you are using an Addon plugin to build the footer.
Often the add-ons are not compatible with the latest versions of Elementor, although we do give the developers a heads-up on code deprecations on developers.elementor.com, regardless of that when you are using 3rd party Elementor addons updating should be done carefully.
Unfortunately, we cannot provide support or control of third-party plugins.
Please try contacting the author of your plugin, for extra guidance, not sure if you are using this specific plugin, but if you are using a free WP plugin it should have
a support forum, like this:

Lastly, try to rule out a theme conflict by switching your theme (temporarily) to a default WordPress theme such as Twenty Twenty One and see if it makes any difference.
Using the Hello theme to create a somewhat custom footer should also work.
Hope it helps you.
