根据报错，看起来是「Encryption algorithm support missing」这个错误导致了 MySQL 服务器启动失败。MySQL 8.0 版本默认启用了「InnoDB Tablespaces」加密特性，但是服务器缺少了入口支持该加密算法，因此导致 InnoDB 初始化失败和服务器异常退出。
解决方案可以尝试关闭 InnoDB Tablespaces 加密特性，具体可以在 MySQL 配置文件中添加以下参数：
innodb_encrypt_tables=OFF
或者在启动 MySQL 命令中添加 --innodb_encrypt_tables=OFF 参数，重新启动 MySQL 服务即可。
