Unclear issue when trying to build the site #3014
Description
Hi, on two different machines (one macOS, the other Ubuntu with a fresh install of mkdocs), when I try to build the site, I get these very unclear error messages. Would anyone have an idea if the issue is with the mkdocs files or python itself?
Running python 3.10 on the Mac, 3.8 on Ubuntu. Latest version of mkdocs and materials installed. The YAML file was validated, but it is encoded in ASCII and multiple attempts to convert it to UTF8 have mysteriously failed.
It also fails when compiling with GitHub Pages, which is why I tried to debug this on my laptop. There were a few changes made to the code by removing a plug-in I believe, but even if I download old commits that used to build and publish just fine do not work on my computer or on Ubuntu.
I'm really at a loss here.
