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?

    Not sure if you are still trying on this, but I am still trying to learn more about it.

    I managed to recreate your situation, but have not been able to recover from it yet. Searching online does not find a lot about this and most who try to fix it end up needing to do a Windows Reset to fix it.  A few post things that appear to work in some cases, but none have worked for me yet.  The "parent features" required are still a mystery to me at this point.

    There are many people run into the exact same problem in Chinese community. What I know is that my solution works out and no one report the deprecated thing.

    Okay, I never go this far, maybe let's try remove '/All' command and do it again? Seems no '/All', no parent features needed.

    Like this:

    Dism /online /Enable-Feature /FeatureName:Microsoft-Windows-NetFx3-OC-Package

    Dism /online /Enable-Feature /FeatureName:Microsoft-Windows-NetFx4-US-OC-Package

    Dism /online /Enable-Feature /FeatureName:Microsoft-Windows-NetFx3-WCF-OC-Package

    Dism /online /Enable-Feature /FeatureName:Microsoft-Windows-NetFx4-WCF-US-OC-Package

    I think maybe PkgMgr.exe has been deprecated in your system while it exists in system in cn language. Let’s try command dism instead of pkgmgr, which means the content in bak file is:

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

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

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

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

    And run it as admin again, let’s see if there is difference.
