Hi GianluigiSellitto-2979,
Thanks for sharing the workaround.
In addition, MDAC/WDAC components might be removed in future releases, and no new features will be added to components in MDAC/WDAC and it isn't recommended to use them for new application development. And when you upgrade or modify existing applications, remove any dependency on these components. Please refer to this article which might help.
Best Regards,
Amelia
