Hello @chandapukiran, Thank you for creating this issue and the actions/setup-python repository does not support x64 packages for Python <3.11 version on macOS arm64 runners due to compatibility and build issues. The build process for Python versions less than 3.11 involves downloading the official Python sources from python.org and building them using the make tool on the oldest available version of macOS that was available when that Python version was released. This is done to ensure backward compatibility for those Python versions as mentioned in this python-versions documentation.
However, this build process can run into compatibility issues on macOS arm64 runners. The arm64 architecture is used in Apple's newer Mac models that use Apple Silicon processors, which are based on a different instruction set than the x86-64 processors used in older models.
Therefore, the built Python packages for versions less than 3.11 may trigger the issues like few modules missing on macOS arm64 runners. This is why the actions/setup-python repository does not support x64 packages for <Python 3.11 versions on macOS arm64 runners.
For Python versions 3.11 and onwards, the actions/setup-python repository uses the official macOS universal2 Python binaries from python.org, which are compatible with both x86-64 and arm64 architectures. These can be used on macOS arm64 runners without any issues.
For Arm64 platform, we use official macOS universal2 Python binaries and provide only versions which are provided by Python org.
Please feel free to reach us needed to reopen this issue for more clarifications.

Hi @aparnajyothi-y , we use X86 based Mac OS
ProductName: macOS
ProductVersion: 13.5.2
x86_64

Does the issue occur only with ARM based or X86 as well ?

Hi @aparnajyothi-y , we use X86 based Mac OS ProductName: macOS ProductVersion: 13.5.2 x86_64

Does the issue occur only with ARM based or X86 as well ?

x86_64 means you use x64, not x86.

However, installing Python 3.10 on Mac OS 13.6.5 x86_64 causes the same error as you have.

- uses: actions/setup-python@v5
  with:
    python-version: '3.10' 

UPD.
Changed Python to 3.11, and got infinite install step

Hello @chandapukiran, @AShunevych , Thank you for the response and for Python versions less than 3.11, the official Python sources are downloaded from python.org, built using the make tool, and archived along with the installation script for further distribution & installation which will raise compatibility issues on both x86-64 and arm64 architectures. Please refer to this documentation.

@AShunevych We have tested python3.11 package on macos-13 and it is successful. Please find the screenshot for reference and can you please share the workflow details to check the issue and assist further.
