 > The current implementation (in WordPress 6.3) is currently causing the
 asset generation and concatenation to fail with an HTTP 503 error if less
 than 1.5 Gb RAM is assigned to the site. See
 https://github.com/WordPress/gutenberg/issues/54294 for fuller details.

 #47322 is a ticket with a simple patch that likely reduces peak memory
 usage for `wp-admin/load-styles.php`.
