Unable to install exoplanet using Conda Forge

[mjl192]

Describe the bug
Conda is unable to install exoplanet (unable to solve for environment specs). Seems like there is some kind of version incompatibility, I get the following code in error:
Channels:

• conda-forge
• defaults
  Platform: osx-arm64
  Collecting package metadata (repodata.json): done
  Solving environment: \ warning libmamba Added empty dependency for problem type SOLVER_RULE_UPDATE
  failed

LibMambaUnsatisfiableError: Encountered problems while solving:

• nothing provides python >=3,<3.7 needed by contextvars-2.1-py_0

Could not solve for environment specs

└─ pin-1 is not installable because it requires
└─ python 3.12. , which conflicts with any installable versions previously reported.

To Reproduce
conda install -c conda-forge exoplanet

Expected behavior
exoplanet should download and be able to function in Jupyter and other anaconda applications.

Your setup (please complete the following information):

• Version of exoplanet: 0.5.2
• Operating system: MacOSX Sonoma 14.7.2
• Python version & installation method (pip, conda, etc.): Conda v24.11.2 via Anaconda Navigator, details below.

Additional context
I'm very much a rookie with python still, so apologies if this is a really easy fix that I've just not been able to find myself!

Solved by reverting to Python v3.8.20.
