I'm now getting a recursion error in scientific-python/cookie after the latest release:

<repeats till Recursion error>
If I run it manually instead of in CI, where I'm pre-loading the answers, instead I get a KeyError:

KeyError: 'project_name'
Template
https://github.com/scientific-python/cookie
To Reproduce
To see the KeyError:
uvx --with copier-templates-extensions copier copy gh:scientific-python/cookie package --trust --vcs-ref=HEADOr to see the RecursionError:
uvx --with copier-templates-extensions copier copy gh:scientific-python/cookie package --trust --vcs-ref=HEAD --defaults --data=project_name=cookie-hatch --data=org=org --data=backend=hatch '--data=full_name=My Name' --data=email=me@email.com --data=license=BSD --data=vcs=False
Using copier==9.7.0 also fails. But copier==9.6.0 works correctly.

Why is uv not listed above? ;) Over 20% of all package installations from PyPI are now through uv (as of a week ago).
