Octane freezes C4D when "tri:0 NodesXXXX" shows in LV

[marco_py]

I have a fairly heavy scene project which my GPU's can normally handle (2X RTX 3090). This scene is similar to other project files I have, with different cameras etc.
However on this scene when I render to the LV, I wait for "Export Materials" to finish, then it shows "tri:0 NodesXXXX Updating" continuously and c4d freezes.
Most of my similar projects show roughly "tri:0 Nodes1300 Updating" and they work fine, showing up in the LV, but this scene doesn't work.

The only way to get it to work is if I open the Octane texture manager, wait for all the materials to load and show the image resolution, then it will work.
This means if I add it to the render queue overnight it will just crash C4D unless I do this step first.

Try disable multithreading for material creation.

I already have that disabled yeah

Keep to see Console window for any outputs during the process. Look for any error outputs. Last message may be the clue before freeze.

I think the culprit is the texture compression mode,
anything other than "automatic" causes it to randomly do this on many projects
