Back end media library display problem

[jontubmen]

I'm using WordPress 6.72, and the media library is not showing any images from my library in grid mode, so I'm not able to insert featured images into posts.
I have disabled all plugins and it is still broken. The front end works fine. The site is at ​https://sunrooms2.com/

Welcome to your first ticket, Jontubmen! 🎉 We’re excited to have you on board.

Could you please try the following steps to help troubleshoot the issue?

Switch to a Default Theme – Activate a default theme like Twenty Twenty-Four to rule out theme-related conflicts.
Check Your PHP Version – Ensure you're using PHP 8.0 or higher for compatibility.
Check for Console Errors – Open your browser’s developer tools (F12) and check for JavaScript errors in the Console tab while loading the media library.
Enable Debug Mode – Add the following to wp-config.php:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Afterward, check the log at wp-content/debug.log for any errors.
Confirm Theme is Up to Date – Make sure your theme is the latest version.
Looking forward to your findings! Let me know if you need any help as you go along. Again, welcome aboard! 😊
