Worked: this was happening on 2.91.x and I downloaded the newest version to see if the issue was resolved. I occasionally get farther through the troubleshooting steps below, but functionally cannot use this scene.
Short description of error
Blender Crashes completely. This has happened when adding a particle system to a plane, modifying an existing particle system on the same plane, or modifying the second particle system if I manage to get through the process of adding it without a crash.
Exact steps for others to reproduce the error
The crash has happened repeatedly and incredibly consistently, though sometimes happens earlier in the steps and sometimes later.
- Open attached blender file.
- Select object "troublemaker-plane"
- change settings in particle system. changing the "emission" number up or down, adjusting the clumping under the "children" section, or adding a force in the viewport (harmonic or wind) can all cause the crash.
- if you've done any of the above and no crash, select "troublemaker-plane" and add a new particle system and name it. this has caused a crash.
- change the new particle system type to hair, change "render as" to collection" and choose the "tulips" collection. this has caused the crash.
- if there continues to be no crash, change the emission number for the new particle system to something reasonable, 20-40. attempt to select and grab one of the particles. this has led to a crash.
at no point has my computer's ram been more than 20-30gb out of 64 used. rarely if ever have the fans been on to indicate that the machine was working hard. the file is quite small (~1mb) and while there may be some optimizing, much larger files (~200mb) are running perfectly using similar particle systems and shaders.
