grimmThank you very much for the info.
Just one thing to mention: it is the wrong thread for this bugreport.
As not only it is about
Linux version of plugin, but even Octane engine and plugin versions are absolutely different in current Linux plugin release, so the reasons are rather absolutely different.
Moreover, as I already wrote earlier - especially Linux version of Octane SDK has some fluctuating bug which we so far can't reproduce on our side in debug sessions (it seems it is bound to network usage somehow)... But after I will return from vacation I will spend some effort especially to catch this Linux SDK bug.
Regarding these last Windows releases - there may be absolutely different reason of crashes mentioned here, as these 3.x versions were refactored very much to use new Octane engine, so there may be some little bugs as the consequence of this big rework (bugs which don't exist in current Linux version)...
So, it may be helpful if some Windows users who has
exactly this version of plugin installed, would post here the messages of Blender console after the crash...
