installation – why cannot install python >= 3.10

I have the below error reporting and cannot solve by searching the internet:

I have tried below code in my zsh:

(ethos) zhangzhongheng@zhangzhonghengs-MacBook-Pro ethos-paper % conda install python=3.12.6
Channels:
 - conda-forge
 - defaults
Platform: osx-arm64
Collecting package metadata (repodata.json): done
Solving environment: failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - nothing provides tzdata needed by python-3.12.6-h8f8b54e_0_cpython

Could not solve for environment specs
The following package could not be installed
└─ python 3.12.6**  is not installable because it requires
   └─ tzdata, which does not exist (perhaps a missing channel).
