Hi, I am Dave, I will help you with this.
The most successful method to install version 24H2 is to use the Windows 11 ISO.
Please follow the steps, this is then not like re-installing Windows, it is just like an update and your personal files, settings and installed software will not be affected.
You will need minimum 40GB of free space for the update.

to download the Windows 11 ISO
When the ISO file completes downloading
Disconnect from the Internet
Disconnect all external devices with the exception of a mouse or keyboard.
Temporarily disable any 3rd party Anti-virus you may have installed
Then, in Windows File Explorer, double click the ISO and then run Setup.exe and select the Install option.
