System Information
Operating system: Ryzen 7
Graphics card: RX Vega 56

Blender Version
Broken: 2.80 beta closes the app

Worked: (optional)

Creating second particle systems shut down the app.

Short description of error

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

create a plane
subdivide it 100 times
add textures
upload file with rocks (and add them to new collection)
use them as Hair particles
Set them the way i needed
Upload anothe file with 1 rock
create new collection for it
choose terrain and add one more particle system
breaks the app

I can't reproduce this on my end.

Could you provide the exact blender version you are using (hash and build date)? These are available on the splash screen.

Additionally could you attach a minimal .blend file that has this issue? So I could for example open that file and begin on step 9

Hello, Sebastian

Sorry, I have forgotten one more step. U should choose "Hair" particle sysmem.

I have attached my file so u can add particle system and choose Hair.

I'm guessing this in render related.
