Stuck PC insider update 14971 at 22%.

[Neo Nuke]

The update is able to download and gets stuck at 22% after the restart. I cannot go back to the older versions and it says my original windows 10 anniversary update is missing. Not sure, if and when a new PC insider update comes it'll see it and attempt that one or I'm going to have this downloaded update on my machine forever with it never being able to install.
Suggestions? should I get an ISO for an older build and install that?
