Fatal Error in Version 2.5.1

[Gameink]

After updating to version 2.5.1, this fatal error occurs immediately when the plugin is active. The site becomes completely unusable.

[Tue Jul 22 04:47:16.109212 2025] [php:error] [pid 213162] [client 10.2.72.100:58298] PHP Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, bool given in /var/www/html/wordpress/wp-content/plugins/shibboleth/shibboleth.php:580\nStack trace:\n#0 /var/www/html/wordpress/wp-includes/class-wp-hook.php(326): shibboleth_l>[Tue Jul 22

Please let me know if I can provide additional information to help.

I will fix this. Sorry about that. I wonder why it didn't fail for me.

Should be fixed by 2d26721 and will be released momentarily as 2.5.2
