Hello, I am trying to conduct preprocessing analysis for my new dataset. The workflow I have was working great with my previous dataset but now for this new one, I am getting error messages. I am attaching the workflow along with the error I got and sample data and would be glad if you can help me to figure out what the problem is. I really appreciate your help in advance!

I have seen such problems before. You could try to do a clean start of KNIME once.

KNIME start with -clean option in knime.ini
