已经找到原因了，打开Gutenberg 编辑器就会报错，关闭就不会报错。

可以复现

在启用gutenberg时使用新版的采用区块编辑器的/wp-admin/widgets.php随便插入一个区块（不是legacy widgets里的，其是禁用gutenberg时在widgets.php添加的那种旧版小工具）并保存就会导致

There was an error. Cannot read properties of undefined (reading 'hasOwnProperty')

/wp-includes/js/dist/edit-widgets.min.js：

本质上是因为/wp-json/batch/v1的后端返回了http400 The provided widget type (id_base) cannot be updated.错误

这个错误来自 https://core.trac.wordpress.org/browser/tags/6.0.2/src/wp-includes/rest-api/endpoints/class-wp-rest-widgets-controller.php#L552

罪魁祸首找到了：https://github.com/seatonjiang/kratos/blob/dc88428c960dcfa77fc7ad7ef0fb59203e0732a4/inc/theme-widgets.php#L37-L56 https://developer.wordpress.org/reference/classes/wp_widget_block/

这个问题已经修复了，由于在经典模式禁用了WP_Widget_Block，所以在古登堡模式会出异常，更新主题版本即可修复。
