Bug

Some sites might see a fatal error around class BlockPatterns.php, with the website not loading. This was due a bad response from Woo pattern repository. A fix was deployed to the repository but certain sites might still have a bad cache value.

Fix

Updating to 9.8.4 will fix the issue.

Workaround

Sites seeing this fatal can fix it by removing this transient ptk_patterns via WP CLI if that's still accessible to you or from the database directly.

 wp --skip-themes --skip-plugins transient delete ptk_patterns

or deleting _transient_ptk_patterns from the DB: (change the wp_ prefix to your db prefix)

DELETE FROM wp_options WHERE option_name = '_transient_ptk_patterns';

If you can't edit the database, modifying plugins/woocommerce/src/Blocks/BlockPatterns.php and adding this inside parse_categories will fix it:

	/**
	 * Parse prefixed categories from the PTK patterns into the actual WooCommerce categories.
	 *
	 * @param array $patterns The patterns to parse.
	 * @return array The parsed patterns.
	 */
	private function parse_categories( array $patterns ) {
		if ( ! isset( $patterns['categories'] ) || ! is_array( $patterns['categories'] ) ) {
			return array();
		}

The issue has been fixed from the cache source side but certain sites were left with a bad cache value, we will be releasing patch updates to fix that.
