Since Plesk comes with such an old version of Magento you probably can't use PHP 8.1. If you want to use the latest version of Magento you'll need to install it from source. It looks like Magento 2.1.0 provided by Plesk supports up to PHP 7.0, but not higher than that. The extension mcrypt was removed in PHP 7.2 I believe so that would explain why it's still looking for that.

The latest version of Magento is 2.4.5 released a month ago.

The version of Magento provided by the Plesk installed is 2.1.0 which was released in 2016 and reached end of life over 3 years ago.

okay sir please change my Php setting open_basedir to None at this time my open_basedir setting is 

{WEBSPACEROOT}{/}{:}{TMP}{/}
please change it to None i need to install CS Cart Shop

Open_basedir prevents you from accessing files in other people's accounts. We will not be setting it to none because then you could access other people's files which would be both a privacy concern as well as a security vulnerability. If you need open_basedir disabled you'll need to get a VPS.
