I’ve experienced this issue on several sites of my client that use Elementor as a page builder, not sure what happened exactly but here’s the various ways I did, hopefully it works on your end too.
Refresh the page
Most occasionally I just did a refresh on the page and it fixed the issue, I suspect there was the running process happening at the same time that eats up RAM, so the PHP can’t process your image resizing request.
Adjust Memory Allocation Both in PHP and WordPress
Raise the memory limit to add more Memory to the PHP, you can do that by updating the php.ini file, look for this value; “memory_limit” and change the value to a higher number.
memory_limit = 512M
If you are on cPanel, you can edit this value by going to php options / php ini editor.
Also you need to tell WordPress about the memory limitation raise, add this line into wp-config.php
define( 'WP_MEMORY_LIMIT', '256M' );
