This is expected. Check prerequisites. Airflow on Windows can only be installed with WSL2:

https://airflow.apache.org/docs/apache-airflow/stable/installation/prerequisites.html

Airflow™ currently can be run on POSIX-compliant Operating Systems. For development it is regularly tested on fairly modern Linux Distros and recent versions of MacOS. On Windows you can run it via WSL2 (Windows Subsystem for Linux 2) or via Linux Containers. The work to add Windows support is tracked via #10388 but it is not a high priority. You should only use Linux-based distros as “Production” execution environment as this is the only environment that is supported. The only distro that is used in our CI tests and that is used in the Community managed DockerHub image is Debian Bullseye.
