On a whim, I tried “sudo yum install -y php56-gd” and now it works. The issue was with the version.

I completed a fresh install of WordPress on a new server and also tried cropping an existing image that comes with the WP installation. Cropping still fails.

Any other ideas?

Thank you for the link. I enabled debugging. Unfortunately, no additional messages were generated.

$ grep DEBUG wp-config.php
* It is strongly recommended that plugin and theme developers use WP_DEBUG
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
define(‘WP_DEBUG_DISPLAY’, true);

I described most of this in my post. I just tried resetting the plugins folder per the link you posted, and that had no effect, either.
