Same issue. The WooCommerce update from 8.4.0 to 8.5.0 caused a Fatal error (copied below).

WP plugins include: WooCommerce + Woo Subscriptions + WooPayments (Theme: Hello Elementor)

Rolling back to WooCommerce 8.4.0 via full site & database backup solved the issue for now.

I turned off auto-updates for WooCommerce–related plugins and am waiting to update to WooCommerce 8.5.0 until there is a fix from WooCommerce.

Fatal error: Uncaught Error: Using $this when not in object context in /home/customer/www/website.com/public_html/wp-content/plugins/woocommerce/src/Internal/Features/FeaturesController.php:340 Stack trace: #0 /home/customer/www/website.com/public_html/wp-content/plugins/woocommerce/src/Internal/Admin/Marketplace.php(23): Automattic\WooCommerce\Internal\Features\FeaturesController::change_feature_enable('marketplace', true) #1 [internal function]: Automattic\WooCommerce\Internal\Admin\Marketplace->init() #2 /home/customer/www/website.com/public_html/wp-content/plugins/woocommerce/src/Internal/DependencyManagement/Definition.php(59): call_user_func_array(Array, Array) #3 /home/customer/www/website.com/public_html/wp-content/plugins/woocommerce/src/Internal/DependencyManagement/Definition.php(29): Automattic\WooCommerce\Internal\DependencyManagement\Definition->invokeInit(Object(Automattic\WooCommerce\Internal\Admin\Marketplace)) #4 /home/customer/www/website in /home/customer/www/website.com/public_html/wp-content/plugins/woocommerce/src/Internal/Features/FeaturesController.php on line 340
