Can't update module astropy in an environment

I'm running Anaconda with an environment phd, and I'm trying to update astropy to the current version (5.0.4, same as in my base environment).

>>> conda activate phd
>>> python
Python 3.7.1 (default, Oct 28 2018, 08:39:03) [MSC v.1912 64 bit (AMD64)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import astropy
>>> print(astropy.__version__)
4.3.1

In the base environment, I get

>>> python
Python 3.9.12 (main, Apr  4 2022, 05:22:27) [MSC v.1916 64 bit (AMD64)] :: Anaconda,
Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import astropy
>>> print(astropy.__version__)
5.0.4
>>>

I've tried conda upgrade astropy from within phd, and conda update --name phd astropy, both of which return

Collecting package metadata (current_repodata.json): done
Solving environment: done

# All requested packages already installed.

Retrieving notices: ...working... done

What am I doing wrong?

conda astropy virtual-environment python

Python 3.7 is not supported. Unless a Python package is designated as noarch - astropy is not -, a build must be made for each Python version. A maintainer of the Conda Forge astropy feedstock dropped support for Python 3.7 in Nov. 2022. This was consistent with the documented requirements of astropy, that show version 5+ requiring Python 3.8+.

If you would like to use the newer versions of astropy then create a new environment with a more recent version of Python. I would not recommend upgrading Python in-place, since most packages will have to be replaced anyway.
