Battlefield 5 bans

From 2020 to June 2024, the game was banned. I have been playing and running steadily for four years. But in June, the game was suddenly banned. I don't know why. I have played for nearly 1000 hours in online mode or stand-alone mode. After I was banned, I was busy for work and family reasons, so I didn't have time to complain. Since this year, I have been complaining, but the official response was like that sent by a robot, and didn't clarify when and why my account violated.
