How to change the language in Aftereffect 2020?

Hello eyeryone.

I downloaded Aftereffects in Japanese from Creative Cloud. But if you do it, an empty error screen comes out and it changes to English.For reference, I use Korean window10.

I tried in the same way as above, but it didn't work.

Is there anyone who has the same problem as me? please help me..
