Hi, good day! I'm John Dev a Windows user like you and I'll be happy to assist you today. I know this has been difficult for you, rest assured, I'm going to do my best to help you.
If your current Windows 11 version is 23H2, it is not mandatory to install 24H2 because your version will reach end of service in November 2025. Wait for it to be offered in Windows Update and you don't need to uninstall anything.
