I have tested with 14.0.3 of Gutenberg Plugin, need to test with further version to see where this gets fixed. When sites auto update to WordPress 6.1 and you have an older version of Gutenberg plugin installed the site fatally breaks with an error as follows Fatal error: Cannot redeclare get_template_hierarchy() (previously declared in ...../wp-includes/block-template-utils.php:1310) in .....c/wp-content/plugins/gutenberg/lib/compat/wordpress-6.1/block-template-utils.php on line 312 Once this happens the users cant access the frontend or the backend to deactivate the plugin. Solution : Rename or remove and install the latest version of Gutenberg plugin via FTP." defect (bug) closed normal 6.1.1 Upgrade/Install 6.1 normal fixed has-patch has-testing-info commit fixed-major
