Critical error – still

Hi,
I saw the threads before me, but I have a different critical error to share:

Notice: Function WP_Scripts::localize was called incorrectly. The $l10n parameter must be an array. To pass arbitrary data to scripts, use the wp_add_inline_script() function instead. Please see Debugging in WordPress for more information. (This message was added in version 5.7.0.) in /home/.../wp-includes/functions.php on line 5835

I’m not sure since which version I have this error, as I skipped a bunch, and just updated it yesterday, and the error was there. I also updated the plugin just a few minutes ago, but I still have the error.

I’m using this plugin outside of WP.com. Still, if you could look into this, it would be great.
