My Answer:
It's possible that the issue is related to changes in the WordPress core code that affect how meta box custom fields are saved. Without seeing your code, it's difficult to pinpoint the exact issue, but here are a few things you can try:

1. Make sure that you are using the correct hook to save the meta box custom field. You should be using the `save_post` hook to save the custom field data when a post is saved or updated.

2. Check if there are any changes in the way data is being saved in the meta box custom field. Make sure that you are properly sanitizing and validating the data before saving it.

3. Check if there are any conflicts with other plugins or themes that may be affecting the saving of the custom field data. Try disabling other plugins and switching to a default theme to see if the issue persists.

4. If you are using a custom meta box class or framework, make sure that it is compatible with the latest version of WordPress.

If you can provide more details or code snippets, I may be able to provide more specific guidance on how to resolve the issue.
