WooCommerce adding string of characters to URL

WooCommerce is adding the exact same string of characters to my URL since yesterday. It redirects my website https://www.eshnashoney.com to https://www.eshnashoney.com/?v=c86ee0d9d7ed and affects all my other pages as well (Terms & Conditions page: https://www.eshnashoney.com/terms-conditions/?v=c86ee0d9d7ed)

I know for sure that it’s WooCommerce causing this as I deactivated all plugins other than WooCommerce and the error was still there. But once I deactivated WooCommerce my URL went back to https://www.eshnashoney.com.

Anybody have any solutions?
