Preview and media not working

Hello. I am having an issue with Elementor and Sydney

The logo of the site disappeared suddenly and some pages are missing images and color. Also, live preview is fine but when I click to preview page is lacks in images and color, and I can’t include or edit any image in media, it occurs an error

What can it be?

Thanks
