Before the update, I used to set my Origins's game language to English. Then, I interested to turn it into Japanese. (after 13 August update). 

when it's downloading the japanese in-game language, i paused it. (maybe at 78-80%). Then I delete my windows 10 admininistrator account for some reasons.

in new windows 10 administrator account, I opened up my origin, and load the progress of saved japanese language download data in-game data.
then it's been succeed on finalizing its data.

When I played apex, it is nothing seems to be error, the gameplay was fine, set up skins, open player data etc. was fine. Later, I opened up the "Store" option, "ストア" in japanese, Its able to display the Crown's Exclusive items (Epic and Legendary skins lists). Then, I decided to look up into "Event Store" or "イベントショップ”. Display suddenly become black, and then popped the message that I have listed before. *in what happens when the bug occurs? ⭐.
Although the event store is fine when I opened up in English-in-game-langguage setting.
Despite of that, I want to be able to play and access its game contents even it is in other languages.

so, please fix this problems. with as many as possible ways. thank you so much.

*NB : I have done changes the origins language setting to Japanese also, and tried to repair game files. but nothing changed. still error on accessing the Crown Store. Although, it's able to access it when I used Origin-language settings & in-game-apex-language settings to "English". thank you.
