I found this on cgchannel

"Houdini 19 is also the first version of the software in which Python 3.7 is enabled by default, SideFX having provided parallel Python 3 builds throughout the Houdini 18 release cycle.

According to SideFX, Python 2.7 will continue to be supported “for another release or two” for compatibility with third-party tools that do not yet support the newer version of the programming language."

A 139 denotes a segmentation fault on Unix, which means the application tried to use memory it wasn't allowed to. It might not be the “Alembic delayed load primitives” but something in your env file as well that interferes with the loading.

I suggest making a new render only file that includes only what you need to render. And secondly strip out anything not needed for this render from your env file. You would be surprised what problems can be introduced with plugins and paths.

Well I am not saying this is the best solution but it's a setup and could be a start to a conversation (v18.5.462)
