I will retry considering thisVery nice that you are taking steps to try to solve this! Cheers!
I am not sure that a native asset will produce the bug, because it could be present in the compressed_shader_cache.sack even if you remove it from the Native module.
Can you try with a completely custom asset?
If this proves to be something that you cannot do, I am happy to put together a test module for you with a single item.
