Need Help Removing Stylesheet

I have a stylesheet that is slowing down the site, its from an old theme but I tried the code below to remove it and it crashed the site. The site is not live so cannot link to it.

This is the stylesheet

<link rel=’stylesheet’ id=’xstore-kirki-styles-css’ href=’https://mysite.xxx/wp-content/uploads/xstore/kirki-styles.css&#8217; type=’text/css’ media=’all’ />

This is the code I used :

// disable stylesheet (example)
function shapeSpace_disable_scripts_styles() {
	
	wp_dequeue_style('xstore-kirki-styles');
	
}
add_action('wp_enqueue_scripts', 'shapeSpace_disable_scripts_styles', 100);

Can anyone help me please?

Thanks
