Korean string input error on E-Prime

https://support.pstnet.com/hc/en-us/articles/115001812847-String-Input-30078-

I followed this article when I get Korean string input. I can get English and number very well, but when I write Korean, E-prime just shut down.

I changed IME setting (https://support.pstnet.com/hc/en-us/articles/1500004797881-INFO-Some-Microsoft-IMEs-cause-issues-with-E-Prime-2-0-on-Windows-10-2004-and-beyond-37376-), but it did't solve the problem.

How can I get Korean string input without an error?
