Hi, I am Dave, I will help you with this.
Version 22H2 of Windows 11 reached end of Support on the 8th of October, were you never previously offered version 23H2 to install?
The new version of Windows 11 that was recently released is 24H2, if you are not offered that version, and the Upgrade Assistant did not install that version, was there any error indicated when you tried to use that, like your system was incompatible with 24H2, because it is currently blocked on some hardware configurations.
