Bug description

The optimization plugin does not work, it crashes with an error at startup:

WARNING - Config value 'dev_addr': The use of the IP address '0.0.0.0' suggests a production environment or the use of a proxy to connect to the MkDocs server.
However, the MkDocs' server is intended for local development purposes only. Please use a third party production-ready server instead.

INFO - Cleaning site directory

Optimizations:
FileNotFoundError: [Errno 2] No such file or directory: '.cache/plugin/optimize/images/assets/images/favicon.png'

Adding favicon to the assets/images/favicon.png folder does not solve the problem.

Only adding an image to '.cache/plugin/optimize/images/assets/images/favicon.png' Fixes this problem, but it's a clear crutch.
