From what I could tell, the astra_header_woo_cart_configuration function was simply not loaded before it was invoked in this code path. My only course was to downgrade to 4.4.1 (prior to recent WooCommerce-related theme changes), which does not exhibit this problem.

This issue was separately reported by another user in https://www.ads-software.com/support/topic/wpadmin-application-customize-there-has-been-a-critical-error-on-this-website/.
