1) Stop MySQL

• Stop it in XAMPP Control Panel. Ensure no mysqld.exe is running (Task Manager).

2) Backup

• Copy the whole folder: C:\xampp\mysql\data to somewhere safe.

3) Repair all Aria tables (offline)

• Open PowerShell as Administrator and run:powershellcd 
• C:\xampp\mysql\bin Get-ChildItem -Recurse C:\xampp\mysql\data -Filter *.MAI | ForEach-Object { .\aria_chk.exe -r $_.FullName }
• # Explicitly repair the system plugin table as well
  .\aria_chk.exe -r C:\xampp\mysql\data\mysql\plugin.MAI

4) Delete Aria log segments

• Do NOT delete aria_log_control.powershell
• Remove-Item C:\xampp\mysql\data\aria_log.* -Force -ErrorAction SilentlyContinue

5) Start MySQL

• Start from XAMPP Control Panel and check the log.

If you still get “Could not open mysql.plugin table”:6) Restore only the plugin table from XAMPP’s backuppowershell

Copy-Item C:\xampp\mysql\backup\mysql\plugin.* C:\xampp\mysql\data\mysql\ -Force

• Then try starting MySQL again.

7) After it starts, check and optimize tables (optional but recommended)powershell

# If root has no password, omit -p

C:\xampp\mysql\bin\ mysqlcheck.exe -u root -p –auto-repair –optimize –all-databases

Notes

• These steps keep your data intact; the only files removed are the Aria log segments that MariaDB can safely recreate.
• If MySQL still won’t start, repeat step 3 for any database folder that shows errors during aria_chk, then re-run step 4 and try again.

If this above is not working try following ways
This is a MySQL/MariaDB database corruption issue in your XAMPP installation, specifically with the Aria storage engine. Here’s how to fix it:

Solution Steps

1. Stop MySQL Service

• Open XAMPP Control Panel
• Click “Stop” for MySQL (if running)

2. Backup Your Data (Important!)

Before proceeding, backup your database folder:

• Copy C:\xampp\mysql\data to a safe location

3. Delete Aria Log Files

Navigate to your MySQL data directory and delete the aria log files:

C:\xampp\mysql\data del aria_log.*

4. Run Aria Check and Repair

Open PowerShell as Administrator and run
C:\xampp\mysql\bin
.\aria_chk.exe -r C:\xampp\mysql\data\mysql\*.MAI
