 * Server: local.
   WordPress: 6.3.1JetPack: 12.6.1
 * The text of the error is very long. I indicate only the parts that are most important:
 * Notice: Function jetpack_register_block was called incorrectly
 * trigger_error( $message = ‘Function WP_Block_Type_Registry::register was called
   incorrectly. Block type names must not contain uppercase characters.
 * WP_Block_Type_Registry->register( $name = ‘jetpack/C:\wamp64\www\artehistoria\
   wp-content\plugins\jetpack\extensions\blocks\business-hours’, $args = [‘render_callback’
   => ‘Automattic\Jetpack\Extensions\Business_Hours\render’, ‘editor_style’ => ‘
   jetpack-blocks-editor’] )
 * The error persists with all plugins disabled. I have also changed the theme, 
   but the error remains.
