Hi, the render crashing issue is a bug in Blender 2.80 that we are waiting for the Blender developers to fix. See this document for more info an possible workarounds: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Blender-2.8-Support#bug-render-crashes
Locking the interface often helps with rendering (Blender > Render > Lock Interface).
