Critical Error when updating low stock notification

  • Hi,
    My client has been experiencing a critical error when changing the low stock level. What happens is after updating the stock level threshold, he gets a critical error message, then when trying to do the same update it goes through. This has happened a few times. Any insight into what might be the problem?

    Here’s the error message that WordPress generates from the crash:

    WordPress version 5.5.3
Current theme: Goodnow Farms (version 1.0.0)
Current plugin: Back In Stock Notifier for WooCommerce | WooCommerce Waitlist Pro (version 1.9.9)
PHP version 7.3.22-1+ubuntu18.04.1+deb.sury.org+1

    Anyone have any insight as to what’s going on with this? I thought I had resolved the problem by updating WordPress to v5.6, but I’m still seeing crashes. This one is an “Uncaught Error”. Here’s the error message from the Woocommerce status log:
