E_ERROR was caused in line 751 of the file class-product-sync.php

Hi, with Awesome Support plugin activated, I cannot edit Products anymore. Or rather: modifications are not saved. I’m getting error reports like these :

An error of type E_ERROR was caused in line 751 of the file /home/xxx/wp-content/plugins/awesome-support/includes/class-product-sync.php. Error message: Uncaught TypeError: array_filter(): Argument #1 ($array) must be of type array, string given in /home/xxx/wp-content/plugins/awesome-support/includes/class-product-sync.php:751
