Builds: Plugin infinite loops on FLandscapeRenderSystem::BeginRenderView()

Hi… plugin is halting in the FLandscapeRenderSystem::BeginRenderView()… typically 3.2 seconds and then on shutdown engine issues a “Fatal Error”

Does not replicate in editor, builds only (development)

happens quite often… especially when moving around… I have no issues on builds without the plugin
I’m not using origin shifting as the project extents is about 10 x 10km

attached is a Insights Log for reference… cheers. Jamie
