My computer is in chaos right now because I tried to update Python. I updated to 3.11.4 and all of a sudden a bunch of packages are having issues. Specifically, gala is unable to be installed entirely.
I've tried completely uninstalling Anaconda Navigator and completely re-installing it. Then when I run "pip install gala" it like runs for a really long time in CMD and prints a bunch of "DEBUG" info then says "Solving Environment:" and has the waiting symbol for literally ever. Like last time it was 3 hours that I finally gave up and shut it off. It never ends. When I try to downgrade Python to what I used to use with Gala (3.8.8) it does the same thing and refuses to downgrade Python (using conda install python=3.8.8). What on Earth do I do? I literally started from scratch even and this is bad because all my work is dependent on this package :(
Everything was working fine before I tried updating packages.
Tried uninstalling Anaconda Navigator entirely and re-installing. Packages aren't working. Python refuses to downgrade. I don't know if there is some issue in my computer or what.
Here's the end of the error message (the actual error is pages long):

note: This error originates from a subprocess, and is likely not a problem with pip.

And here is a message that comes a bunch of times for various packages within gala:
############################
# Package would be ignored #
############################
Python recognizes 'gala.tests' as an importable package[^1],
but it is absent from setuptools' `packages` configuration.
This leads to an ambiguous overall configuration. If you want to distribute this
package, please make sure that 'gala.tests' is explicitly added
to the `packages` configuration field.
Alternatively, you can also rely on setuptools' discovery methods
(for example by using `find_namespace_packages(...)`/`find_namespace:`
instead of `find_packages(...)`/`find:`).
You can read more about "package discovery" on setuptools documentation page:
- https://setuptools.pypa.io/en/latest/userguide/package_discovery.html
If you don't want 'gala.tests' to be distributed and are
already explicitly excluding 'gala.tests' via
`find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
you can try to use `exclude_package_data`, or `include-package-data=False` in
combination with a more fine grained `package-data` configuration.
You can read more about "package data files" on setuptools documentation page:
- https://setuptools.pypa.io/en/latest/userguide/datafiles.html
[^1]: For Python, any directory (with suitable naming) can be imported,
even if it does not contain any `.py` files.
On the other hand, currently there is no concept of package data
directory, all directories are treated like packages.
