I believe we need more information about your issue.
What is possible to say at the moment is that you are trying to set propeties of undefined variable.

Getting this error sometimes for scene.render()

And it is hanging the whole UI

4

Can you repro in the playground, I do not see how this can happen ?

5

Can it happen if we have multiple meshes with same name ?

6

Again, we’d need a repro to understand what’s going on

The issue was due to corrupted valued in Mesh .rotation
