JS Regex Crashing

Hoping someone can point me in the right direction with this. I'm making a little Grunt task that requires some CSS be split up using regex.

Here is an example of the regex in question working as expected:

For some reason however, when I run this as part of my grunt task it crashes terminal.

var regexString = new RegExp("^((?:\.|#)(?:[a-z]|[A-Z]|[0-9]|\s|\.|#|-|:|&|,)+?{(?:\s|\n)*(?:\/\*export\*\/)(?:.|\n)*?})", "gm");
var splitString = css.split(regexString);

I've tried countless variations but I can't seem to figure out what exactly is going on, any help appreciated!

You need to escape the backslashed \s and \n to \\s and \\n as they are inside a string (or use the unquoted // syntax).
