"However, I cannot use simple code in the. csx file to demonstrate that this error occurs again. Although the code is marked with a red line, it can run successfully."

I have found a problem that when I add the '# load" xxx "statement, a red line error occurs. If it is not present or commented out, no red line error occurs.
