Your version of Python might be pinned to something far too recent. Try Python 3.10, or in general avoid directly pinning onto 3.13.
Also it may be better to manage your own Python using conda/Miniforge with a consistent set of libraries (not many are needed for Amber install, just a few packages iirc) and disable Miniconda in the run_cmake config options.
