There’s is an error due to an issue with the theme

Good evening,

The problem on my website store is because of the theme. It doesn’t let the people see the product, buy it or anything else.
You’ll understand that it is an urgency because rightnow nobody can but anything.

The error is the following one:

HP Fatal error: Uncaught Leafo\ScssPhp\Exception\ParserException: parse error: failed at $text_color_button_hover: ; (stdin) on line 16 in /srv/htdocs/wp-content/themes/uray/inc/admin/sassphp/src/Parser.php:128
