Thank you very much for your advice.
What I don't understand is that there is no problem when executing ① alone or ② alone,

It works well when i let the application sleep after ① for 10 seconds before executing ② .
Is this true for large numbers of lines in you csv? Originally you said something like 'adding 1000 lines' broke your app. Are you using CopyManager?
