Rhino crashes when attaching a worksession

Hi I am experienceing an issue where Rhino crashes when attaching a worksession. This seems to have only started occuring in the most recent update (I have worked with these file before without any issues) and only applies to large files (>300MB).

I was finally able to successfully attach the workession by opening the file separately and turning most of the layers off, but this was much slower that previously.

There doesn’t seem to be any computer resource spikes at the time of crash and there is no crash report to send to McNeel.

Is it possible to roll back to the previous version of Rhino?

Version: Rhino 6 SR13 (6.13.19058.371, 27/02/2019)

Hello - can you please run SystemInfo in Rhino and post the results?

Hello - can you please open Options > Plug-ins page, and locate the Vray and Tibidabo plug-ins, disable it (check box) and the restart Rhino - does that change the worksession behavior at all?


Hi Pascal.
It doesn’t seem to be any faster or more stable when the plugins are disabled.

i work with several 300-700mb worksession attachments all the time, no issues with the recent updates.

Hello - just to make sure - Rhino is starting from scratch with these three plug-ins already disabled:

Tibidabo LandsDesign

correct? And Worksession > Attach crashes Rhino?
