Hi there,
Not sure if this was reported in the past. Cosmos seems to cause 3Ds Max to crash abruptly and without a warning. I am currently using VRay 5.23 on MAX 2020 - I don’t use Cosmos and the crashing isn’t caused by trying to access it. It just happens randomly, it seems.
From the max.log I could pinpoint that Cosmos is the issue since it always shows a warning right before the max file crashes.

Uninstalling Cosmos didn’t help and reinstalling VRay didn’t help either. Any thoughts?
