**System Information** Operating system: Darwin-17.7.0-x86_64-i386-64bit 64 Bits Graphics card: AMD Radeon HD 6970M OpenGL Engine ATI Technologies Inc. 4.1 ATI-1.68.25 **Blender Version** Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-09-17 21:51, hash: `rBcacd57b67a15` Worked: (newest version of Blender that worked as expected) **Short description of error** Blender crash when you select Grid Display > 'Obstacle Levelset' or 'Outflow Levelset' in Fluid Simulation without 'Obstacles' or 'Outflow' objects in Scene. **Exact steps for others to reproduce the error** **1**. Open a new default file. **2.** Select the Cube object in the scene and add a Fluid > Domain > Liquid type. Mark the 'Mesh' chekbox in the Liquid panel. Mark 'Is Resumable' chekbox in the Cache panel. **3.** Add an object (ex. sphere) and add a Fluid > Flow > Flow Type --> Inflow, (rest of settings default). **4.** Play the simulation (Cache type > Replay, rest of settings default). **5.** Pause the simulation and Mark the ' Grid Display' chekbox in 'Viewport Display' panel. Select Field > Obstacle Levelset or Outflow Levelset. **6.** Blender crash immediately. Keep in mind that there aren't 'Obstacles' or 'Outflow' objects in the scene.
