The Open Cart site "death" due to uncomprehensible PHP error

The company avtoVIRA sells equipment for tow trucks/auto service stations and warehouse trolleys through its own website avtovira.com.ua (WordPress + WooCommerce, versions UA/RU/EN) and Prom.ua. Diagnostics through Google Search Console showed: out of ~879 known Google pages, only 423 are indexed, and 456 are not indexed. The majority of the unindexed pages (262 out of 456) are technical junk from WooCommerce (parameterized URLs: ?add-to-cart=, ?wc-ajax=, ?filter_vantazhopidjomnist=), which consumes Google's crawling budget and hinders the indexing of real content. The goal of the task: to eliminate the technical reasons for the incomplete indexing of the site so that real product and category pages (specifically the line of warehouse trolleys) consistently appear in Google's search results.
