After update, Uncaught Error

Hello,

after updating, I tried to make some changes through the view editor, but there was an error notice in the View window, and I cannot make any changes.
Query monitor shows:

Uncaught Error: Call to undefined function WP_Filesystem()
in so-css.php on line 93.

I am not sure how to fix this.

Line 93 of my so-css.php file shows:

if ( empty( $post_id ) && WP_Filesystem() ) {

and line 91-94:

function get_custom_css( $theme, $post_id = null ) {
$css_key = ‘siteorigin_custom_css[‘ . $theme . ‘]’;
if ( empty( $post_id ) && WP_Filesystem() ) {
$custom_css_file = apply_filters( ‘siteorigin_custom_css_file’, false );

Same problem om my staging site that runs a different theme.

Help is really appreciated!
