Updating to Gradio 4.18.0 causing TypeError: cannot pickle 'dict_keys' object

[samadwar]

Describe the bug

It seems Gadrio 4.18.0 is causing an issue where I get the below error, same code works with v4.17.0.

As I work around I had to pin gradio version to 4.17.0. It seems the issue is related to adding deepcopy in routers.py (see here)

Agh I was worried about this. I have an idea for a workaround. I’ll try it tomorrow
