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?

    Same exact problem, same exact build and update .. although I went in and turned a few features back on in components, not I cant access all of my control panel...

    Do you have any remaining .NET features in Control Panel? If so, the pkgmgr fix might help.

    I found this documented on the Visual Studio .NET Developer Community Forums since January, 2019 and it is the most upvoted Problem there.

    I even did a Windows Reset, but the results were no better than your in-place upgrade. .NET still looks the same, with several items misplaced in the list of available Windows Features. Even MMC cannot load the Event viewer now.

    That leaves a clean install as the only way forward that I can suggest.

    It's certainly looking that way, Don. I'm now seeing more & more reports of this issue in the Feedback Hub too. No response from MS on any of the feedback though.

    Wonder if this will end up making it through to the 1903 release & they'll end up with yet another major issue for a small percentage of users (which still adds up to a large number of people) that was reported as a serious bug in the feedback hub but never actioned?
