Error when uploading SVG image in the header

I’m trying to switch my png header image to a svg.
TEst site is here: Cboard
To upload the SVG in the WP library I used this snippet below (maybe this is the problem):

//Allow SVG through WordPress Media Uploader
function cc_mime_types($mimes) {
  $mimes['svg'] = 'image/svg+xml';
  return $mimes;
}
add_filter('upload_mimes', 'cc_mime_types');

The svg file is showing in the library but after selecting it and clicking on the option select and crop, on the next click “crop” I get an error “Problem resizing the image”

Any idea how to solve this problem?
Simone is uptodate, no fancy plugins installed, child theme in place.

Thanks,
