Win10 to Win11: Both 'PC Health Check' & 'WhyNotWin11' say my PC is compatible, but Windows Update says it is not

Another first-time poster here, so I apologize if this is the incorrect format/forum.

My issue is that both Windows' PC Health Check and WhyNotWin11 say my PC is compatible with Windows 11, but Windows' actual Update settings say it is still not compatible (both pictured below).

Upon crawling some threads, I found some advice on a previous one from @Bree that fixed this 'internal check' issue by deleting the GE24H2 and GE25H2 keys in the Registry via:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\TargetVersionUpgradeExperienceIndicators

However, the 'GE24H2' and 'GE25H2' keys do not actually present in my registry. (also pictured below)
I am sure this is a silly user issue, but I can really use the advice of someone who knows better than I do.

This is the link to that previous thread who had a similar issue: Win 10 to Win 11 - Win 11 Health Check says PC is compatible, Windows Update says it is not

Thank you

What happens when you upgrade using Windows 11 setup.exe from ISO image or using Windows 11 Media Creation Tool?
