Hello,
If you want to run the fresh WordPress installation you can use WordPress Database Reset plugin https://wordpress.org/plugins/wordpress-database-reset/
XStore studio allows import sections from different demons, when you are using Elementor plugin. Just edit page using Elementor > click here – https://prnt.sc/udpfle and import the desired block. But if you are using WPBakery Page Builder, do not enable the Elementor, watch this video – https://youtu.be/wkIKN2IyEZI
