Error Creating New Posts

HI. This morning myy site, SeriousInsight.net was not able to create a new, empty post. It could create a duplicate post (via JetPack's feature) but not a new one.  Here is the error code:

I reached out to WPEngine and their bot said The error is likely caused by a conflict or issue with the Kioken Blocks Premium or Gutenberg plugin. I disable Gutenberg, and it now works. Are you aware of this issue? What do I need to do to make Kloken and Gutenberg play nice? Thanks!!
