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?

    1. creat .bak file, the content is:

    start /w pkgmgr /iu:Microsoft-Windows-NetFx3-OC-Package

    start /w pkgmgr /iu:Microsoft-Windows-NetFx4-US-OC-Package

    start /w pkgmgr /iu:Microsoft-Windows-NetFx3-WCF-OC-Package

    start /w pkgmgr /iu:Microsoft-Windows-NetFx4-WCF-US-OC-Package

    1. run as admin
    2. solve the problem

    Even though pkgmgr is deprecated, it does not mean that it does not work.  The syntax that you used could be crucial, as the "start /w pkgmgr /iu:" portion of each command is significantly different than just running the commands without that syntax.

    I am able to run each command line without error, as long as I use that exact syntax.

    I have never seen that ".NET Environment" option that you show at the top. I wonder where that came from. My build 18362.53 does not have the "ASP.NET 4.8" either. Do you think ASP.NET has anything to do with this?

    Actually, your entire group of .NET has different names than mine.
