Fatal error (WC_Data_Exception) Admin note content prop cannot be empty (4.0.1)

Hi there,

Following updates recently, a development site has started to produce the WordPress fatal error page shown below. This is a cPanel environment on CloudLinux 7, with this website running under PHP 7.3 with all usual extensions enabled and options set to suit decently busy websites.

“There has been a critical error on your website.
Learn more about debugging in WordPress.”

Looking at the PHP error log, this seems to stem from WooCommerce and potentially an admin note field/insertion/etc catching an exception. It seems unlikely that this wouldn’t already be known about via other users though.

This website runs lean with regard to plugins, and those that it’s running are all well-known and/or reputable. The active theme is Divi (licensed).

PLUGINS // Installed & active

• Disable Comments
• Price Per Unit Pro
• WooCommerce
• WooCommerce Admin
• WooCommerce Gateway – Stripe
• WooCommerce Gateway – PayPal Express Checkout

Could someone at Automattic or in the WordPress community please offer some assistance? It’d be very much appreciated.

Many thanks,
