The scarlet Letter can be found from the log, telling us that we can't read and write the Ibdatal file ... If the file can not read and write, it should be your manager's authority problem, the solution is to find the XAMPP installation directory to set the contents of this folder to the administrator has the highest permissions.

Workaround:

1. Open the Task Manager to terminate the MYSQLD process;

2. Open the Data folder of the MySQL installation directory and delete the following 2 files:

Ib_logfile0 and Ib_logfile1

3. Restart MySQL
