Media library not showing images

Hello, I’m having an issue with photos in the media library. When I have the “list” mode set, the photos display correctly. However, in the “grid view” mode, they don’t show up. I’d appreciate any advice.

I’ve tried the following steps, but none of them helped:

• Changed the PHP version.
• Updated everything, including WP and plugins.
• Deactivated all plugins.
• Switched the theme to the default one.
• Deactivated the .htaccess file.
