Hi @Kaii,

It seems like the application add an additional data driver and oracle connector has recognized it has been deprecated and can't be used to connect to data source.

I'd like to suggest you check the oracle data driver settings to configure and install correspond data drivers if it has been overwritten by the added applications.
