Enabling a context block reaction mangles node display

Hello,

I'm encountering a strange behavior whenever I enable a context rule in D8 and am wondering if anyone else has encountered anything similar or would have an insight on where to begin troubleshooting.

I created a context with condition=node type and reaction=block. When that rule is enabled, the block is placed correctly but:

-- all other blocks that have been placed (via the block system) disappear, and in effect the entire site wrapper (header and footer vanish. Please see attached screenshots before and after context rule is enabled.

This occurs no matter what theme is enabled, or what block is chosen or where it is placed in the reaction. The error log displays a series of errors along the following lines when this occurs. but I am having a hard time figuring out what may be happening, see below.
