JS Error: “Cannot create property ‘guid’ on string ‘.dropdown-menu.show’

Hello,

I am encountering a JavaScript error that is breaking functionality on my website. The error is related to jQuery and occurs when attempting to interact with elements that use the class .dropdown-menu.show. Below are the details:

jquery-migrate.min.js:2 JQMIGRATE: Migrate is installed, version 3.4.1
jquery.min.js:2 jQuery.Deferred exception: Cannot create property 'guid' on string '.dropdown-menu.show' TypeError: Cannot create property 'guid' on string '.dropdown-menu.show'

The error appears to be related to an interaction between the jQuery migrate script and custom JavaScript code for Bootstrap 4 smart menus. This issue occurs consistently across different browsers, and updating to the latest versions of all plugins, themes, and WordPress itself has not resolved the issue.

Steps to Reproduce:

1. Load the affected webpage.
2. Interact with any dropdown menu that uses the class .dropdown-menu.show.
3. Observe the JavaScript console for errors.

Browser/Environment:

• Browser: [e.g., Google Chrome 114]
• Operating System: [e.g., Debian 12]
• WordPress Version: 6.6.1
• jQuery Version: 3.4.1

Please let me know if you need any additional information or if there’s a known solution to this problem.

Thank you!
