I have this same error. Temporarily resolved it by deactivating the WooCommerce Admin plugin. I have the latest version 2.0.1. Before deactivating this plugin, I tried changing the a standard theme, and then deactivating all my non-WooCommerce plugins. It still failed. So I reactivated them and then deactivated the WooCommerce Admin plugin and the error is gone. So is there a fix coming for this?
WordPress version 5.6.1
Current theme: Divi
Current plugin: WooCommerce Admin 2.0.1
PHP version: 7.4.14
