Is it possible to Editing a Blender file without opening it to remove a crashing node?

Hello everyone,

I have a Blender project that crashes due to a specific node tree when I try to open it. I attempted to append the node tree into another project, but it immediately causes the new project to crash when applied to an object.

So I thought that modifying the file code without opening it might be a solution. But I have no idea how to go about it…

This is the node tree where the issue come from :

and this is the node group inside the node tree that cause ths issue :

Thanks in advance for your help!

There is a Python module called blendfile.py for parsing Blend files.
I never used it to modify a Blend file, but I think it’s your best bet.
This might not be helpful, but it’s the only method known to edit a Blend file outside of Blender.
