[SOLVED] Twine/PyPI - Invalid distribution file

I am trying to upload my package (SyntenyQC) to test pypi as described here via Anaconda prompt.

I have installed twine and build as described in the link, and got a dist folder with a wheel and gz file. However, twine errors with Invalid distribution file.

I am copying my token via right-click not ctrl v (avoiding this error). I noticed that the printout of twine is slightly different from that of the tutorial, which may be relevant:

tutorial in link:

Uploading distributions to https://test.pypi.org/legacy/
Enter your username: __token__
Uploading example_package_YOUR_USERNAME_HERE-0.0.1-py3-none-any.whl
...

my traceback

Uploading syntenyqc-0.0.1-py3-none-any.whl
...

My full traceback is below. I suspect the issue may be that I am installing from within a venv (pip_env) so will try repeating everything from my base env. In the meantime, can anyone else suggest any obvious fixes?

Thanks!

EDIT

running in my base environment with fresh installs of build, twine and hatchling gives me a new twine error :( :

(base) C:\Users\username\.spyder-py3\SyntenyQC>python -m twine upload --repository testpypi dist/*
Uploading distributions to https://test.pypi.org/legacy/
ERROR    InvalidDistribution: Metadata is missing required fields: Name, Version.
         Make sure the distribution includes the files where those fields are specified, and is using a supported Metadata-Version: 1.0, 1.1, 1.2, 2.0, 2.1, 2.2.

EDIT 2

Updating pkginfo fixed the error in edit 1, leading me back to the same initial error </3

EDIT 3

Twine can't find any issues with the files, so not sure what the issue is:

(base) C:\Users\u03132tk\.spyder-py3\SyntenyQC>twine check dist/*
