Erroneous system compatibility report in 26.3.0 build 87

On updating AE to 26.3 and launching I got a system compatibility warning saying “This version of windows is no longer supported, future versions of this app cannot be installed on this OS.” 

When I click for more info it takes me to the Premiere system requirements page. 

From the generated system compatibility report, my versions of Windows is being reported as 10.0.22631.1 which I believe is fully up to date.
