Class not found after upgrade to v2.1.4

Hi!
I’m having this error after upgraded the plugin to the latest version (2.1.4)

`Uncaught Error: Class ‘VSWC_Upgrader’ not found in /var/www/wp-content/plugins/variation-swatches-for-woocommerce/includes/class-menu-page.php:12
Stack trace:

Extra env info:
WordPress 5.9
Supro Theme
Plugin: Variation Swatches for WooCommerce (version 2.1.4)
PHP version 7.3.30

I was reading similar type of issue in other plugins. That might be the upgrade process doesn’t finished correctly and as expected. But I want to confirm with you.

Thank you!
