Lightning Out after Spring 18 on CS77

Good Morning, Smart Folks!

It seems that our Lightning Out app which is embedded in a Sitecore site has completely stopped working after the application of Spring 18.  Everything worked GREAT(ish) on Friday the 5th Before the update was applied.  Now, I'm getting two Javascript errors when trying to render the app.  (It doesn't even hit our custom, its not our app, and a simple "Hello World" lightning app does the same thing. 

Here's the Chrome dev tools output:

aura_prod.js:formatted:23327 Uncaught TypeError: Cannot read property 'create' of undefined

Hi! This is happening for me as well. Any help would be appreciated! After attempting a simple static lightning out app, I'm getting the same results.

I had same problem I found out some of the tags were not working
here is my small suggestion for your case.
If you are using lightning:formattedNumber or any other tags which are in beta try to remove them and use any other equivalent tags that may help
