Error 500: Class ‘WC_Background_Process’ not found

Hello,

Installing this plugin causes an error 500 right after the activation.
Error is :

[12-Jul-2018 11:35:07 UTC] PHP Fatal error: Class 'WC_Background_Process' not found in MySite\wp-content\plugins\wc-vendors\classes\includes\class-wcv-background-updater.php on line 14

It seems that the class ‘WC_Background_Process’ is loaded by Woocommerce, I can see it in the plugin code (doc).

Environment :
– Woocommerce Version 3.2.5
– WC vendors Version 2.0.10
– WP 4.9.1
– PHP 7.1, Laragon, Windows 10

I can send the full woocommerce report privately.

Thanks for your help !
