Magento paypal buy not available in product page

[arulkailasam]

In Magento, I'm using the Breeze Evolution Theme. In the Magento_Paypal module, there is a component called paypal-sdk.js that contains the following code:

define(['jquery'], function ($) {
var dfd = $.Deferred();
});

This code throws an error because the $ object does not contain the Deferred function, although it does have other functions and properties. When I visited the demo website for the Breeze Evolution theme provided by the vendor, the $.Deferred() method is available there.

I'm not sure if I missed any configuration during the theme installation that might be causing this issue. Could you guide me on how to fix this problem?"

What's the version of your swissup/module-breeze? $.Deferred function was added in 2.14.1.

Please provide URL to your site if Breeze is up to date.

Thank you for your time and assistance with my question.
In the Magento root directory, I ran the command composer show and found the following version details:
swissup/breeze-evolution - 2.1.5

Could you please provide guidance on the next steps I should take to resolve this issue?

It's too old version. You need to update Breezefront using composer update command.

When I ran the command composer update, I received the following error message:
