I am getting the error Call to undefined function mcrypt_module_open(). After upgrading the virtuemart to latest 3.4.5 from 3.0.9.

Shop is not accessible, even in back end if I tried to save any thing in VM configuration this error comes.

PLease help.

Joomla version is 3.9.4.
I am doing the changes on XAMPP server locally.
