Installer breaks if username is not in English / With non-english locale?

First of all, I am sorry through the translator because I am Korean.
The current problem is that there is an error during installation through the mode installer.
TypeError: '>=' not supported between instances of 'UnicodeDecodeError' and 'int'
It's an error statement written on the terminal.
- My operating system is [Windows]
- I installed the game [2 weeks ago]
- I am trying the [Full Patch]
- I installed the game [using the Automatic Installer (steam)]
- My computer is a [Gaming desktop]

Sorry for asking Github, not discode, because I am not good at English.
I ran it in Safe Mode, but the error came out the same.
I really want to do it, but I don't know what to do. Please help me.

該錯誤表明安裝腳本中存在 Unicode 處理問題，很可能是在處理非英文使用者名稱或地區設定時發生的。請查看安裝程式的主要進入點，並追蹤檔案路徑或使用者輸入被解碼的位置。檢查字串比較或編碼假設。透過在測試系統上設定非英文使用者名稱或地區設定來重現錯誤，以找出解碼錯誤的根源。
