On large menus the php serialize method in \libraries\src\Cache\Controller\OutputController.php function store() causes apache server to restart.
Even with cache disabled.

The complete menu object is serialized before a check is made if cache is enabled.
On large menu's (roughly +150 menuitems, probably more settings play a role) this causes my Xampp server to restart.
Check if cache is enabled before performance intensive actions, like serialize, are executed.

Steps to reproduce the issue

Build a menu of +150 items
Got to a page in the website where this menu is displayed using mod_menu module.

Expected result

Menu is displayed.

Actual result

Server keeps restarting and finally causes timeout
Troubleshooting and logging is difficult, because the server is restarting.
Firefox returns:
Secure Connection Failed
An error occurred during a connection to www.website.dev.
Error code: PR_CONNECT_RESET_ERROR

System information (as much as possible)

Xampp server PHP 8.1 and 7.4
Apache 2.4
memory_limit=512M and memory_limit=8192M
Joomla 4.2.5

Additional information

Adding the cache check in function store(), before cache lock is checked and object is serialized (quick)fixes the issue.

    public function store($data, $id, $group = null, $wrkarounds = true)
    {
		if(!$this->cache->getCaching()):
			return false;
		endif;

        $locktest = $this->cache->lock($id, $group);
