Php error after a couple of hours

[larnoult]

Wordpress 5.8.2 multisite install, CiviCRM 5.43.2.
Shoreditch and Shoreditch WordPress Workarounds installed.
After activating this extension, civiCase works great on Wordpress... but only for a couple of hours.
After that, a Php fatal error happens on every pages (back and front). WordPress error message (debug mode true) is

Fatal error: Uncaught Error: Class 'CRM_Civicase_Helper_CaseSetting' not found in /www/parlemonde_330/public/wp-content/uploads/civicrm/ext/uk.co.compucorp.civicase-symbiotic/settings/CiviCase.setting.php:16 Stack trace: #0 /www/parlemonde_330/public/wp-content/plugins/civicrm/civicrm/Civi/Core/SettingsMetadata.php(109): include() #1 /www/parlemonde_330/public/wp-content/plugins/civicrm/civicrm/Civi/Core/SettingsMetadata.php(92): Civi\Core\SettingsMetadata::loadSettingsMetadata('/www/parlemonde...') #2 /www/parlemonde_330/public/wp-content/plugins/civicrm/civicrm/Civi/Core/SettingsMetadata.php(66): Civi\Core\SettingsMetadata::loadSettingsMetaDataFolders(Array) #3 /www/parlemonde_330/public/wp-content/plugins/civicrm/civicrm/Civi/Core/SettingsManager.php(220): Civi\Core\SettingsMetadata::getMetadata(Array) #4 /www/parlemonde_330/public/wp-content/plugins/civicrm/civicrm/Civi/Core/SettingsManager.php(102): Civi\Core\SettingsManager->getDefaults('domain') #5 /www/parlemonde_330/public/wp-content/uploads/civicrm/ext/firewall/ in /www/parlemonde_330/public/wp-content/uploads/civicrm/ext/uk.co.compucorp.civicase-symbiotic/settings/CiviCase.setting.php on line 16

We were chatting online about this - and while debugging I found this:

$ wp civicrm api extension.refresh
PHP Fatal error:  Uncaught Error: Class 'CRM_Civicase_Helper_CaseSetting' not found in /www/public/wp-content/uploads/civicrm/ext/uk.co.compucorp.civicase-symbiotic/settings/CiviCase.setting.php:16

Related to the firewall extension which does this:

function firewall_civicrm_config(&$config) {
  _firewall_civix_civicrm_config($config);
  // Defaults are not loaded until *after* hook_civicrm_config is called by default
  \Civi::service('settings_manager')->useDefaults();
  $firewall = new \Civi\Firewall\Firewall();
  $firewall->run();
}

So it seems like a bit of a catch-22 between settings and the PHP include path not being set (because hook_civicrm_config from civicase has not yet run at that point).
