This is a really strange error. I admit. I have no clue currently what’s happening in your environment t it behaves like this.
how does tox -e test behaves ?

Are there any steps to prepare tox (except installing it) that are not documented somewhere and I might have missed?
$ tox -e test
test: internal error

I might have found a hot trail. Totally independent from tox and pydoctor I accidentally observed a similar error using hatch to create a virtual environment. The error output of hatch (see below) is bit easier to read so I realized the problem is about the package virtualenv. I uninstalled it via python3 -m pip uninstall virtuelenv. Then hatch worked.
Then I tried tox on pydoctor. And it worked.
I am not enough into the details about virtual environments or the package virtuelenv. So I am not able to decide where and if I should open a bug report. Maybe related to pypa/virtualenv#2551.
Maybe I encountered the first time a real use case why I should use virtual environments. Currently I do avoid them as much as possible. I am a but stubborn about this topic. 😄
