Hello, I'm trying to upload a project with the problem.
As far as I've tested, I found 2 kinds of "projects". With this I mean two differents ways octane behaves, lets call them "Normal" mode and "Weird" mode.
The "normal" mode is octane working as usual.
But in the "weird" mode, I've found some diferences. The biggest difference is the octane node editor. When you press the "View source" button in material "A" it works as intended, the window opens and nothing wrong happens.
But if you select a different material, the node editor closes all the tabs, and you have to press the view source button again. (This is actually something good because I usually get flooded with older tabs, and closing tabs one by one is tedious)
The thing is, I've got the crash problem only when the node editor works in the "weird" mode. I don't know if this information is useful or not, but I'm telling you in case it helps in any way).
So far this is what i've researched about the problem.
