That's really ODD -- because this KB was only a minor security update, both for builds 18362 and 18363 -- so those should not have posed any serious issues.
You COULD check this section of the community Windows 10 forum -- as it deals with individual Windows Updates as they come out: https://www.tenforums.com/windows-10-news/
Other than that, you probably have no choice other than to try to back out that update. This is certainly NOT the first time that MS has pushed out a Win10 Windows Update that caused problems.
