"hatch test -py 3.14 --cover" crashes with IndexError
Even though I have 3.14 included in tool.hatch.envs.test.matrix in pyproject.toml,
I get a crash when running hatch test -py 3.14 --cover. It's specific to 3.14 and --cover.
$ hatch --version
Hatch, version 1.14.2
[[tool.hatch.envs.test.matrix]]
python = ["3.12", "3.13", "3.14"]
$ hatch test -py 3.14 --cover

PR https://github.com/pypa/hatch/pull/2080 fixes it for me.
Further testing shows that hatch test -py 3.14 (without --cover) just exits without doing anything. Same fix.
With hatch hatch-1.16.2 I also have issue with 3.14.2 installed via py with the installed python (and scripts) not in path.
Now when I try to run py -m hatch test on pyawaitable to run the tests to debug why it fails in the github actions for meson I get this error as well:
(Note: I do have 3.12 installed as well, but never installed 2.7...

AttributeError: 'typing.Union' object has no attribute '__module__' and no __dict__ for setting new attributes
On Windows I got this to work by first going into the Installed Apps within Settings and Uninstalling every single version of python that was NOT installed by the new Python Install Manager. After that go to %AppData%\Python\ within the bar right next to the search box in Windows explorer by pasting that text in EXACTLY. Once there delete every last one of the Python??? folders leaving only shared.
Once that is done type in py -m pip install --upgrade hatch to reinstall hatch and it's dependencies prior to running hatch test. I still run into issues however with -py 3.14 on it creating the environment but other than that it all works.
