原因为：MariaDB 的 Aria 存储引擎在非正常关闭后，日志序列号（LSN）不一致，导致每次启动都"期待"下一个编号的日志文件，但实际没有正确初始化。
修复：
在 PowerShell（以管理员身份运行） 中执行：
# 1. 确保 MySQL 已完全停止
taskkill /f /im mysqld.exe
# 2. 删除所有 Aria 相关文件（关键！包括控制文件）
Remove-Item -Force "你的路径\xampp\mysql\data\aria_log.*"
Remove-Item -Force "你的路径\xampp\mysql\data\aria_log_control"
# 3. 【重要】确保 mysql 系统表不依赖 Aria（使用 MyISAM）
# 如果你之前恢复过 backup\mysql，这步可跳过
# 否则请执行：
# Remove-Item -Recurse -Force "D:\...\data\mysql"
# Copy-Item -Recurse "D:\...\backup\mysql" "D:\...\data\mysql"执行后在XAMPP，点击Start,成功启动。
