Blank Page is coming

[vishne0]

We have installed the plugin on Magento 2.3.3 CE after installation when go to configure it, it shows a blank page. In logs we can see main.CRITICAL: Warning: Invalid argument supplied for foreach() in /home/mag2/public_html/vendor/aitoc/google-customer-reviews/Block/Adminhtml/Form/Field/Countries.php on line 51 [] []

Can you tell us how to fix this issue?
