This is sounding like a bug. It shouldn’t be possible to set the category such that you can’t edit it.

Indeed

Allow or not accented characters in category slug according to "slug generation method" setting

I think there’s definitely room to improve this in some way. I tried it out and it feels pretty jarring to innocently enter a slug with an accented character, save, and get hit with a broken page you can’t fix until you figure out that setting exists.
