M2.4.3, v1.1.4: Not work with MSI disabled

ISSUE:

In the backend, we get the following error message when you want to look at the product list also under BACKEND > CATALOG > PRODUCTS:

Fatal error: Uncaught Error: Cannot instantiate interface Magento\InventoryApi\Api\SourceRepositoryInterface in /html/magento2/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:50 Stack trace: #0 /html/magento2/vendor/magento/framework/ObjectManager/ObjectManager.php(70): Magento\Framework\ObjectManager\Factory\Dynamic\Developer->create('Magento\\Invento...') #1 /html/magento2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(167): Magento\Framework\ObjectManager\ObjectManager->get('Magento\\Invento...') #2 /html/magento2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(273): Magento\Framework\ObjectManager\Factory\AbstractFactory->resolveArgument(Array, 'Magento\\Invento...', NULL, 'sourceRepositor...', 'Bss\\ProductGrid...') #3 /html/magento2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(236): Magento\Framework\ObjectManager\Factory\AbstractFactory->getResolvedArgument('Bss\\ProductGrid...', Array, Array) #4 /html/magento2/vendor/magento/framewor in /html/magento2/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php on line 50 

Unfortunately, we come to the conclusion that we don't want to/can't use the magento_inventory extension.

SOLUTION:

Our module has not worked properly with the site disabling MSI yet.

To resolve the issue, please download the file app/code/Bss/ProductGridInlineEditor/Block/Adminhtml/InlineEditor.php attached below to override the current file on your site.
