I updated chrome and there was a problem with the extension, what should I do?

Question

css

Chrome version 59.0.3071.115 (Official build), (64 bit)
I open my extension in developer mode in a tab like this
chrome-extension://iddfgdfggregregrefdjgdfj/popup.html
and all the code is broken, but everything works in the popup window that opens.
Network for css files writes status (blocked: origin), I don't know why and what it means
How can I fix it?
in general, there is an answer,
I didn’t specify the link correctly, I had it like this chrome-extension:
//[email protected]@iddfgdfggregregrefdjgdfj/popup.html
