Check the operator(s) before the cross validation. You can set a breakpoint on the operator that's connected to the input of the cross validation by pressing F7 or right-clicking it. The error message is clear: The incoming table doesn't have regular attributes. Can you put a screenshot of that table or its metadata (Statistics view) here?

I see you're doing text mining (sentiment analysis). This is not the data structure you need for that.
Please watch the videos in the Academy: https://academy.rapidminer.com/catalog?query=text mining
They explain how you preprocess the data for Naive Bayes to correctly identify the attributes for building the model.
