Can you please try the following:
1. Check your `php.ini` file and ensure that the value for `zend.max_allowed_stack_size` is set to `-1`. This is a new feature in PHP 8.3, and setting it to `-1` may help bypass the issue. More details can be found in the PHP 8.3 migration guide: [PHP 8.3 Other Changes](hidden link).
2. Verify if you or someone else manually set the values for `zend.reserved_stack_size` and `zend.max_allowed_stack_size` to `0`. The default setting in PHP 8.3.x for these values is `0`, but it's worth confirming if these were manually adjusted.
Let us know if you have any questions on the matter.

Yes, but note the following potential risks on WordPress:
Server Overload: Removing the stack size limits might make the site more vulnerable to recursive function calls or resource-intensive operations, which could overload the server.
Crashes or Unresponsiveness: If WordPress or any plugin uses deep recursion (for example, in a large query or loop), it may cause the site to crash or become unresponsive.
Security Risks: Removing such limits can expose your site to denial of service (DoS) attacks if someone exploits a script that causes excessive recursion or memory usage.
That being said, it might be worth testing these changes temporarily to see if it resolves your issue. Just remember to monitor the system closely and revert back if things start to behave unpredictably.

Could you please provide the updated debug log after increasing the value?
I also noticed you are using Cloudflare, so it might help to temporarily disable it, clear the cache, and, if possible, restart the server before running the tests again.

These settings disable the stack size limits, which can present potential risks to security and stability in the long term.
Until we can provide a permanent fix, you have a few options:
1. **Find Proper Limits:**
You can adjust the `zend.max_allowed_stack_size` and `zend.reserved_stack_size` to find values that work best for your setup. The ideal limits can vary depending on several factors, including the number of queried elements and any running plugins.
2. **Apply the Suggested Values:**
You can temporarily keep the values we recommended (`-1` for both settings). However, please be aware that this disables the limits entirely, which can lead to potential security risks, excessive memory usage, or server instability.
3. **Consider Downgrading PHP:**
Previous versions of PHP did not have these specific limits, so downgrading could be another temporary workaround to avoid these issues without the need for stack size modifications.
From what we understand, the issue may be caused by the excessive use of a particular function in your system. PHP could be mistakenly identifying this as infinite recursion, when in fact it is a **finite** recursion. We will continue to work on identifying a more stable and long-term solution.
Finally this values creates 500 internal server error :

To get more information on what's causing this, you'll need to enable full error reporting so we can capture the full error stack. Here's what you'll need to do:
1. Edit the `wp-config.php` file in the root of your WordPress install.
2. Add these lines to enable detailed error logging:
This will log the full error details in a file called `wp-errors.log`, which should help us track down what's going on.
Also, if you noticed any specific actions or steps that triggered this error (like installing a plugin or running a large process), or if you can reproduce it, please let me know.
