I updated to the latest Win 10 feature update v1803 and was then unable to start BIAB.

The initial logo came on screen and then a small 'preparing to install' window appeared behind it, and that was that. I tried a few different ways to start BIAB but nothing worked.

I had this problem with a previous Windows feature update.

For now I have reverted to the previous version of Windows and BIAB is back working.

I've delayed the windows update for 90 days but eventually will have to install, so hopefully this problem will be sorted by then.
