Hello. The error message contains a bit of Korean because I am Korean.
In line 3~4, "다른 프로세스가 파일을 사용 중 이기 때문에 프로세스가 액세스 할 수 없습니다." means "The process cannot access because another process is using the file".
Anyway, I keep getting these errors at irregular intervals, and the error message says "(no variables are lost)" but is it possible that the variable will be lost next time?
What does this happen and how can I fix it?
