Hi, that means either your server is missing some php function or some other plugin conflicts with this one.
If you want to find out the errors, you need to edit your wp-config.php by using a ftp program (or using your hosting control panel, if available) and follow these instructions: https://codex.www.ads-software.com/Debugging_in_WordPress
Basically, change the WP_DEBUG to true instead of false, and it will show the errors on the page instead of a white screen.

If you just want to fix the white screen, you need to remove the plugin.
Again you can use the ftp program or your control panel to navigate to the site files, wp-content > plugins and then simply delete the fast-velocity-minify directory.
I would regardless, be interested on what caused the white screen if possible.
