Plugin causes server time out on large products

Not too sure what exactly is happening, but when the plugin is active on our website (a website with over 10k products (including 50k+ variations)) the server times out when saving products with over 50 variations (and some other attributes set for filters).

This has only started recently, so I’m not sure whether it’s due to a recent update or if it’s because there’s a lot of data being stored for our filters.

Upon deactivating the plugin there are no issues saving the really large products with hundreds of variations, so the cause is definitely filter-related.

Does some sort of data get updated/saved (in relation to the filters) when saving a product? If so, why? And can this be disabled without losing any functionality? It will become a major issue on our site for many larger products, and will essentially prevent us from being able to update them if this plugin is active.

WP & WC are on the latest versions (6.2 & 7.6.1) & Woo Product Filter is on the latest release.

PHP is currently v7.4.
