Short description of error
Hello,
i was trying to displace my emitter with a proximity node that use the scattering object as a target,
and the object seem to be randomly disappearing.

It may be some kind of feedback loop?

See gif and file below

Edit:
it seem that it is coming from a false positive error?
as clicking on the object info node enum will pop-back up the geometry

Your file has a dependency cycle: two objects depend on the geometry of each other. That cannot work and there is not much we can do about it.
I assume it works sometimes and sometimes it does not because the order of evaluation of both objects changes randomly.

I honestly don't fully understand what you are trying to do, but you'll probably have to structure your scene a bit differently to avoid the dependency cycle.
