解决方法

参考http://www.manongjc.com/detail/28-cokdecwjtqjsads.html、https://stackoverflow.com/questions/56847804/xampp-mysql-service-crash-after-reboot

1、点击xampp面板上的Shell按钮进入命令框，输入命令：

mysqld –-console –-skip-grant-tables –-skip-external-locking

2、第一个cmd命令行窗口不关闭，重新在面板上点开一个Shell，再次输入指令：

mysqlcheck -r --databases mysql --use-frm

等命令窗口不再变化，再关闭命令窗口，重新启动xampp，重启mysql，问题解决。
