Here are the steps to recover MySQL data when encountering the “MySQL shutdown unexpectedly” error in XAMPP:

  1. Navigate to your XAMPP installation directory and locate the “mysql” folder.
C:\xampp\mysql
  1. Rename the "mysql/data" folder to "mysql/data_old".

  2. Make a copy of the "mysql/backup" folder and name it "mysql/data".

  3. Copy all of the database folders from "mysql/data_old" to "mysql/data", except for the "mysql", "performance_schema", and "phpmyadmin" folders.

  4. Copy the "mysql/ibdata1" file from "mysql/data_old" to the "mysql/data" folder.

  5. Open the XAMPP control panel and start the MySQL service.

  6. Verify that your databases are accessible and working as expected.

Please note that this is an emergency solution and is not intended to be a permanent fix. It is strongly recommended that you backup your data and consider reinstalling XAMPP to avoid any potential issues with malfunctioning files.
