localstack 0.12.18 fails to install

I am trying to install localstack 0.12.18 on a windows 10 Enterprise machine.

I’m running Python 3.9.0 and pip 23.0.1.

I have downloaded the .tar.gz file directly from pypi.org and installing it via:

pip install C:UsersmeDownloadslocalstack-0.12.18.tar.gz --trusted-host pypi.org --trusted-host files.pythonhosted.org

This is the output:

pip install C:UsersmeDownloadslocalstack-0.12.18.tar.gz --trusted-host pypi.org --trusted-host files.pythonhosted.org

Any ideas on what the solution might be?
