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?

    It would be intriguing and challenging to figure out a .NET repair that works, but the clean install would likely be faster and simpler.

    Thanks again Roger. That allowed the in-place upgrade to work normally, however the .NET issue remains exactly as it was before.

    You're welcome, sorry it didn't work. I guess it's time for that dreadful clean install you wanted to avoid.

    Don't forget to back up important files. Good luck!

    The latest build has a bug (check this thread). If that's the one you downloaded or even if it's not, try cleaning C:\Windows\SoftwareDistribution\Download and disable Windows Search.

    Restart and try again, it should work.

    Thanks for the instructions Roger. Finally got around to trying the in-place upgrade last night and it failed...
