Rename folder mysql/data to mysql/data_old
Make a copy of mysql/backup folder and name it as mysql/data
Copy all your database folders from mysql/data_old into mysql/data (except mysql, performance_schema, and phpmyadmin folders)
Copy mysql/data_old/ibdata1 file into mysql/data folder
Start MySQL from XAMPP control panel
xxxxxxxxxx
1_ Rename the folder mysql/data to mysql/data_old (you can use any name)
2_ Create a new folder mysql/data
3_ Copy the content that resides in mysql/backup to the new mysql/data folder
4_ Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
5_ Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
=> Start MySQL from XAMPP control panel
*************************DONT DELETE ibdata1 FILE*************************
xxxxxxxxxx
exit Xampp server
go to your C:\xampp\mysql\data directory
delete the ibdata1 file
restart xampp server
I also had to delete ib_logfile0 and ib_logfile1 to get it to work

Instead, first try using the MySQL backup folder which is included with XAMPP. So do the next:
1.Rename the folder mysql/data to mysql/data_old (you can use any name)
2.Create a new folder mysql/data
3.Copy the content that resides in mysql/backup to the new mysql/data folder
4.Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
5.Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
6.Start MySQL from XAMPP control panel
And, voilà!

Steps to fix this problem –
1. Stop the XAMPP server, MySQL and Apache
2. Create a backup of the “/xampp/mysql/data” folder using a compression software
3. Rename the “/xampp/mysql/data” folder to “/xampp/mysql/data-old”
4. Create a new folder and name it “/xampp/mysql/data”
5. Copy all folders from the “/xampp/mysql/backup” and paste it to
the “/xampp/mysql/data” folder, which you have just created
6. Copy all the databases from the “/xampp/mysql/data-old” folder
and paste it to the “/xampp/mysql/data” folder
7. Finally copy the “ibdata1” and all of the log files including
“ib_logfile0, ib_logfile1 ” from “/xampp/mysql/data-old”
and paste it to the “/xampp/mysql/data” folder
8. Start MySQL from the XAMPP control panel
9. Go to phpMyAdmin to check if all the databases are available and running properly

# Step 1: Check the MySQL error log
# Navigate to the MySQL error log file and examine it for any specific error messages or clues.
# The location of the error log file can vary based on the operating system and MySQL configuration.
# Step 2: Check for any system-related issues
# Ensure that the server running MySQL has enough resources (e.g., CPU, memory, disk space).
# Check if any other processes or services are interfering with MySQL.
# Step 3: Restart MySQL service
# Sometimes restarting the MySQL service can resolve the issue if it was caused by a temporary glitch.
# Execute the necessary command to restart the MySQL service based on your operating system.
# Step 4: Monitor MySQL service
# Use tools like `top` (Linux) or `Task Manager` (Windows) to monitor resource usage while MySQL is running.
# Look for any spikes, high CPU or memory usage, or other anomalies that might be causing unexpected shutdowns.
# Step 5: Verify MySQL configuration
# Review the MySQL configuration file (typically my.cnf or my.ini) for any misconfigurations or inconsistencies.
# Pay attention to settings related to memory, connections, buffers, or disk-related options.
# Step 6: Check for database corruption
# Run MySQL's built-in database integrity checks or use third-party tools to verify the integrity of your databases.
# If corruption is detected, consider restoring from a backup or try to repair the affected database(s).
# Step 7: Consider updating or reinstalling MySQL
# If the issue persists and you're using an older version of MySQL, consider updating to the latest stable release.
# Alternatively, you may try reinstalling MySQL to ensure all necessary components are intact.
# Step 8: Seek community support or consult MySQL documentation
# If none of the previous steps resolved the issue, it's advisable to seek help from online developer communities or consult the official MySQL documentation specific to your version.
# Note: The above steps are general guidelines and may need adjustments based on your specific setup and environment.
