What happened?

If one makes a mistake in config, for example duplicate keys in a dictionary:

[files]
"./file.py" = ""
"./file.py" = ""

PyScript is not loaded. There's no error or warning, nothing at all, complete silence.
Unless one already knows about this nuance, it's rather difficult to guess what the problem is.

What browsers are you seeing the problem on? (if applicable)

Chrome
