Re-apply for the same type and different purposes after the visa is withdrawn.

You can't ignore the previous visa application, and it is not recommended to change the visa type and purpose at will. It will leave a bad impression on the visa officer. You have no real travel purpose, but you have a serious tendency to emigrate. And why do you need to fill in the non-immigrant visa application form DS- 160 again? Generally, the above information will not change obviously in the short term, unless it is false. The form also reiterated that all information such as visas should be filled in truthfully, because it will be recorded in the United States. Don't try to pay again, and people won't check their previous records. Foreign countries attach great importance to honesty.

Of course, if there is a reasonable reason to change the travel intention, it should be handled according to the actual situation, because the visa officer will definitely ask why it was cancelled the first time, and then the purpose will be different after the second time. If you can express it clearly, then there is no problem.
