Japan translations JSON error

This thread is resolved. Here is a description of the problem and solution.

Problem:
You are unable to save a page translation in Japanese language. When attempting to save, it results in a JSON error stating, 'Updating failed. The response is not a valid JSON response.'
Solution:
1. Check if the issue persists when you disable the WPML plugins and attempt to save the page with Japanese characters.
2. Verify if any third-party plugins might be influencing this behavior.
3. Ensure to back up your database before making any changes.

miroslavP-13	Background of the issue: I am trying to create a translation of a page in JA language. There is no possibility to save it, and I believe there is a problem with the Japanese signs. The translation in JA language was created but cannot be saved unlike all other languages. I need to save the page in any language when I edit some content inside or add a block. I was advised to make changes in the original language and translate using WPML editors. Link to a page where the issue can be seen: hidden link \| hidden link Symptoms: When I try to save the translation in JA language, it throws a JSON error. Instead of normal behavior as in all other languages, I got: "Updating failed. The response is not a valid JSON response." Questions: Why can't I save the translation in JA language? What causes the JSON error when saving the page?

Could you please check if the same issue occurs when you disable the WPML plugins and then save the page containing the Japanese characters? I also recommend verifying whether any third-party plugins might be affecting this behavior. Before making any changes, please ensure that you back up your database first.
