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

    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.

    You could download 18362.53 from UUP dump and do a manual in-place update.

    You won't lose apps or files. Instructions here (1st post, 2nd half) applies to any build number.

    The script will take longer than usual because it will incorporate the CUs into the ISO image.

    What do you see if you run:

    DISM /Online /Get-Packages /Format:Table

    Mine shows that Foundation Package as installed.  That is where the .NET, etc. appears to come from.

    Yep, the Foundation Package shows as Installed:

    Microsoft-Windows-Foundation-Package~31bf3856ad364e35~amd64~~10.0.18362.1         | Installed  | Foundation      | 19/03/2019 4:56 AM

    You could've installed on top like we talked about and be long done with it.  ;)

    That'll absolutely be the next step this weekend. I've seen other posts (talking about earlier builds where this happened), however, where people have tried this & it didn't fix the issue. If this doesn't work, I won't be surprived & will be doing a PC reset.
