XAMP MySQL unexpectedly shutdown after site migration

Hello,

I am using XAMP to build my websites on localhost. But there is this one site that i had backed up using WPvivid plugin. Everytime that i make a clean install of wordpress and then i migrate this website, the operation is a success and it works fine for that particular session that i have not stopped Apache, MySQL and quit XAMP. But when i do quit XAMP,, the next session does not work. It brings the “MySQL shutdown unexpectedly error”. I have been testing this for the past days numerous times and this only happens after i restore this old website. What am i missing out on please. Help needed.

Kind regards.
