Hi, I am Dave, I will help you with this.
Microsoft were testing and adding some more processors, and did add some to the list, they indicate they have now completed testing, and no more processors will be added to the official list.
Your 6th gen processor is not on the supported list, the minimum is an 8th gen processor, they indicate that is due to security functions supported by the processors, there was a method provided by Microsoft using a registry edit to install Windows 11 on unsupported processors, but since they released the 24H2 update, they seem to have blocked that as an option. though some online sites indicate it still works.
