打开洛谷网校会报 $\color{red}\textsf{500 Internal Server Error}$；

打开洛谷有题会报错

An exception occurred while executing 'INSERT INTO user (id, username, email, access_token, refresh_token, roles) VALUES (?, ?, ?, ?, ?, ?)' with params [647454, "Micfong" ...  : SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'micfong2@outlook.com' for key 'UNIQ_8D93D649E7927C74'

不知道是我一个人的问题还是站点问题
