Critical error

Hi team, I am getting a critical error message when I click to edit a custom field post.

I deactivated all plugins except Metabox and Metabox AIO and the critical error is still happening. I am not quite sure what has happened and I would like to seek assistance to resolve the issue.

Below is a copy of the email I got. I wonder if I could request email support so I could give you login details. I would be happy to pay for your time.

Look forward to hearing from you.

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Meta Box AIO.

First, visit your website (https://www.[url removed].co.nz/) and check for any visible issues. Next, visit the page where the error was caught (https://www.[url removed].co.nz/wp-admin/post.php?post=141&action=edit) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.

To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 6.1.1
Active theme: Twenty Twenty-Three (version 1.0)
Current plugin: Meta Box AIO (version 1.16.10)
PHP version 8.0.26
