I don't know if I misunderstood the steps, but I can't reproduce the problem.

You forgot to upload a simplest possible .blend file to reproduce this issue

i can reproduce this issue on linux Blender 2.80-RC3 AMD FX8350, 16GB DDR3, GTX690 2+2 GB VRam- Nvidia drivers 430.34

1 delete default cube
2 add metaball cube
3 decrease the size in the properties editor (in my case near radius 0.37m)
4 blender RC3 freeze

This is because the resolution scales along with the radius (see 74dfe71a46).
So on small radii, you end up with very dense geometry...

Tempted to confirm this, but would like feedback from @mont29 as well...

this work fine now on linux Blender 2.80 f6cb5f5449 (Stable) AMD FX8350, 16GB DDR3, GTX690 2+2 GB VRam- Nvidia drivers 435.17 and
Blender 2.81 e045fe53f1b0, no more freeze or crash, is quite strange, scaling with negative value make disappear metabal cube

Nope, still happening here, try lowering the radius to 0.005, get a coffee :)
