Error when creating a new project

[SirMOB]

After running cookiecutter https://github.com/at-gmbh/at-python-template in my conda environment and after configuration, I get following error:

Error: failed to remove files - [WinError 2] The system cannot find the file specified: 'environment-dev.yml'
ERROR: Stopping generation because post_gen_project hook script didn't exit successfully
Hook script failed (exit status: 1)

Python version 3.11.5
Cookiecutter version 2.1.1 / 2.2.3 / 2.3.1 (I tried multiple versions)

My configuration was:
