Triggers API Updater at build and removes MRTK from the toolbar

[sjaugmented]

Running Unity 2019.4 and using WMR, when building with LightingTools imported, triggers the Unity API Updater. After building, MRTK is no longer in the menu (maybe the Updater is removing it?), and on play I get these errors and my hand inputs are completely gone:
