When I reduce the file input node socket to this

Ok I managed to find the bug, so what happen is, if you create a lot of input channel for File Output Node, it will fail to output the file, so currently it only happen with open exr multilayer output in file output node.

I happen to have same problem in my existing setup, but somehow I can't reproduce. Attached zip will work just expected. Maybe @Hongyu Fu (HF)
if you can check it out again.

Confirm on my side as well, checked on firefox, chrome and ms edge . There is weird number appended after .zip

so this is script that I've come up with

import bpy

ah noted @Philipp Oeser (lichtwerk), let me check, maybe this is good as temporary solution

@Jeroen Bakker (jbakker) We stumble this issue since we upgrade to 2.83 LTS, but I'll run a test on other 2.83 version as well and report here.

@Bastien Montagne (mont29) just curious, will it backported to LTS?

@Bastien Montagne (mont29) yes. it's fixed now in latest 2.90 beta build. Thank you

Don't think it ever worked with proxies, and don't think it's expected to work... In any case proxies are legacy feature now, we keep it around until library overrides have been tested enough, and confirmed to be able to fully replace it, but there is no active development on them anymore.

Not sure I understand? If I create an override hierarchy of the collection, that setting works as expected?

@Richard Antalik (ISS) yes, it's the same behavior

This abc file will cause blender to crash.

@Francesco Siddi (fsiddi) Just checking in. I'm new to this mediawiki and your instruction is quite straight forward. Anyway how do I replicate content on my local docker environment?
