I upgraded to Houdini 19.0.383.
Mantra render works fine, but when I try to render Karma it crashes with this minimal error:

033: Fatal error: Segmentation fault (sent by pid 0)

Here are my setup specs:

Houdini 19.0.383.
Ubuntu 20.04.3 LTS
AMD® Ryzen 9 3900x 12-core processor × 24
EVGA GeForce RTX 2060
NVIDIA-SMI 470.74 Driver Version: 470.74 CUDA Version: 11.4

Does Karma work for anyone with similar specs?

Thanks

Update: I've been informed by tech support that this is addressed in the Houdini 19.0 daily build.
Which should resume next week.
