I'm seeing a jquery conflict using the latest version of the helix system plugin on the article edit pages. When enabled, the article edit buttons for save, save/close, and save/new do not work.

Environment details:

• JStore is not installed.
• Joomla up-to-date
• php 8.0
• JCE Editor up-to-date
• Helix up-to-date

If I disable the helix system plugin, I can save articles.

Error details: Uncaught TypeError: this._addClass is not a function.

Error stems from jquery-ui.min.js in the helix plugin around line 12:

_create: function() { this.containerCache = {}, this._addClass("ui-sortable"), this.refresh(), this.offset = this.element.offset(), this._mouseInit(), this._setHandleClassName(), this.ready = !0 },

Please let me know if you need any additional context.
