XAMPP MySQL database problem

I am working on Microsoft Windows 11. Occasionally (seems random), when I open XAMPP it appears to open an old version of my MySQL database. When this happens, all new information I entered on a previous occasion disappears, with no obvious way of retrieving it - except from a backup. It's a pain because I now have to thoroughly check that the database is correct before I start to add new records. Has anyone experienced this before, or have any ideas how to fix it? I have purposely tried to recreate the fault but can't. It just happens at random when XAMPP is started.
