Thank you for letting me know.
Version 24H2 does have a slow download issue, I’ve noticed this while setting up PCs.
I suggest waiting for it to download completely and closing all open apps. It may take some time since it's essentially installing a new version. That shouldn’t be the case, though, as I remember upgrading from 22H2 to 23H2 didn’t have this slow download experience.
If you continue to have download issues, I suggest performing an in-place upgrade with the option to keep files and apps:
> Download the Windows 11 Installation Assistant from the official Microsoft website: https://www.microsoft.com/en-us/software-downlo...
> Open the tool and follow the on-screen instructions to upgrade your PC.
> Make sure to choose the option to Keep personal files and apps.
> Ensure your device stays plugged in and connected to the internet during the process.

This should resolve the issue and get your system updated to the latest supported version. If you need further assistance, feel free to reach out.
I really hope this information is helpful! :)
