Require Orders Model failed

[sprachrohr]

Hello,

after Updating to VM 3.4.2 i have a problem. Joomla version is 3.9.1.

I have an Backend QuickIcon Plugin, where i require the VM Orders Model.
I used this code:
if (!class_exists('VirtueMartModelOrders')) {
   require(VMPATH_ADMIN . DS . 'models' . DS . 'orders.php');
}

After Update to VM 3.4.2 this code doesnt work anymore. I get a blank page without errors. Even if i fill in the whole path, i get a blank page.

Any suggestions?

Thank you!!!

Best regards
Dirk

maybe try
if (!class_exists( 'VmConfig' )) require(JPATH_ROOT .'/administrator/components/com_virtuemart/helpers/config.php');
VmConfig::loadConfig();

before it

it ensures that the VM config is available and loaded
