Uncaught TypeError: r is not a function

I built a plugin that registers a Gutenberg block that prints a simple Mailchimp form. The plugin works with no issues. But, if I activate Jetpack and try to edit any page or post, I get a blank screen and multiple Uncaught TypeError: r is not a function console errors such as this one with little variations:

editor.js?ver=9.1:6 Uncaught TypeError: r is not a function (https://domain.com/wp-content/plugins/jetpack/_inc/blocks/editor.js?ver=9.1)
    at editor.js?ver=9.1:6
    at Array.forEach (<anonymous>)
    at e.exports (editor.js?ver=9.1:6)
    at f (editor.js?ver=9.1:6)
    at Module.<anonymous> (editor.js?ver=9.1:18)
    at o (editor.js?ver=9.1:1)
    at Object.<anonymous> (editor.js?ver=9.1:18)
    at o (editor.js?ver=9.1:1)
    at editor.js?ver=9.1:1
    at editor.js?ver=9.1:1]

The index.js file in My Mailchimp block plugin imports two SCSS files so the build process is able to create the corresponding CSS files:

import './editor.scss';
import './style.scss';

I found that if I comment out the import './editor.scss' line, Jetpack stops throwing the console errors. So, it seems there’s something in my plugin that is conflicting with Jetpack.

Can someone help me, please? I’m completely lost.

I’m running WP 5.5.3 and Jetpack 9.1 and I have the SCRIPT_DEBUG constant set to true.

Thanks
