Issue was caused by curve orco calculation for rendering being freed curve path and not calculating it back. This left depsgraph in a state that it believed all the object data is up to date but in fact some parts of data was freed by convert blender. Now made it so path is not being freed by render thread. This is rather a workaround actually because ideally render thread need to use copy-on-write here or at least use local cache here. But current logic should be closer to what was happening in previous release.
