updated my screenshot to show the correct tab. Also, this continues to occur in 1.16.40

I've read that but I don't see how it applies. This is a Surface Pro X running Windows 10 Pro, not Windows Mobile. The device supports DirectX 12 (not 10 or below).
I get this on my Microsoft Surface Pro X as well, which also supports DX12. See MCPE-93371
I have seen the updated blog post that now clarifies that Windows 10 Desktop ARM devices are no longer supported. That seems to indicate this is not a bug, but a result of Microsoft/Mojang dropping support for Windows 10 ARM devices, including their own Surface Pro X.
If that's the case, it makes sense to close this one.
