Can't enable .NET Environment in Windows 10 1903

Well, this is a showstopper for me. I'm in the Release Preview ring & installed 1903 (18362.30) yesterday . Update went fine. No issues experienced.

Got a Cumulative Update to install today (KB4495666). Installed it & rebooted. Build is now at 18362.53. .NET framework was disabled & 90% of my applications will no longer run! In "Control Panel/Programs and Features/Turn Windows Features on or off", ".NET Environment" is unchecked. If I check it & hit "OK" it take about 10 seconds & says "Windows completed the requested changes". The .NET Environment, however, is still unchecked when I go back to "Turn Windows Features on or off" & >NET applications still don't work.

I've uninstalled all of the updates installed today (KB4495666 & KB4493478), but .NET is still utterly broken. I've read that this was an issue prior to the release of 18362 to the Release Preview ring but was supposed to have been fixed. Looks like this MAJOR bug was reintroduced with the cumulative update?

    Thanks for the quick reply Don. I tried restarting from Features several times. Says it completed successfully but after rebooting still not active. DISM failed also. My Features list looks like the 2nd (right? I'm on a phone) with the ASP.NET4.8 listed.

    The abnormal list is displaying some sub-features of the missing top-level features. The Parent features have vanished. The Parent features also do not appear in DISM/PowerShell. Even when Disabledor DisabledWithPayloadRemoved, the Features should never vanish from the list that is displayed with DISM /Online /Get-Features /Format:Table.

    In Windows Server you can eliminate all parts of .NET, but there is a command that can restore it all, as long as you can point to the matching WIM file from the Windows Server install ISO as a Source.  This same command does not exist for Windows 10 client and you can't run the command from a server to affect a Windows 10 client.  Below is the Feature list from Windows Server that names some of the .NET Features on Windows 10 that are missing on devices that have this problem.

    Unfortunately this is not Windows server. Is there any way to restore in Windows 10 pro?

    At this point, the only option is a clean install of Windows. Neither a PC Reset nor an in-place upgrade will fix it.

    Well, that ends my participation in Windows Insider. I  will never install another Windows update unless it's been vetted and is -3. How does Microsoft defend a release like this that disables your computer? Is there NO quality control? Totally unacceptable.
