I’m having the same issue when upgrading from Wooocommerce 4.2.2 to 4.3. The following plugins were also updated at the same time:
* WooCommerce Admin
* WP Mail SMTP

The frontend of the website functions, but the backend shows the exception. The Storefront theme has an update (from 2.5.3 to 2.5.8) that is pending. I was able to restore the files from a backup I made prior to the update to keep the admin section of the website from crashing.

The error log is truncated in the email and is as follows:

WordPress version 5.4.2
Current theme: Storefront Child (version 1.0.0)
Current plugin: WooCommerce (version 4.3.0)
PHP version 7.3.19
