Hi
I get same problems on win10 x64 after April 2018 Update,
and I do not manage to repair it only by reinstalling win10 without April 2018 Update.
I hope it will help you

Probably a stupid question, but How do I install it without the April Release? I do seem to find it on the internet, nor do I find a setting during the installation.
Just need to find one win10 install kit before April Release, install without being connected to the internet,
disable all windows updates (you can find how to by Google) and then you can connect.
