ERROR! couldn't resolve module/action . This often indicates a misspelling, missing collection, or incorrect module path

There are two Windows collections: community and Supported. I know that's confusing :(

Looks like you've installed ansible.windows, though you are using community.windows

The fix is:

ansible-galaxy collection install community.windows

ansible 2.9 uses collections different. One way is to add them to the top:

---
- hosts: all
  collections:
    - community.windows

and then later use:

- name: Create a profile for the user
  win_user_profile:
    username: test
    name: test
    state: present

for reference:

• Use Ansible Collections
• collections are backwardcompatible

Dirty: dont do this, but it works.

ansible-config dump |grep DEFAULT_MODULE_PATH

and copy them there (example replace path and name)...

cp -p  ~/.ansible/collections/ansible_collections/community/general/plugins/modules/system/sudoers.py ./library/

Adding below details to your question would be helpful

1. Ansible host operating system
2. Ansible version

I guess, this is error is specific to ansible version. I guess you are using ansible 2.9 version or lower version. whereas, Installing collections with ansible-galaxy is only supported in ansible 2.9+.

Reference link : https://galaxy.ansible.com/ansible/windows ( look into 'Note' section )

You can upgrade your ansible version and give a try.

I got the same error with Ansible 2.9 on Ubuntu 20.04 after install community.general. The solution in this case was installing ansible.posix

ansible-galaxy collection install ansible.posix

as this contains the mount module https://docs.ansible.com/ansible/latest/collections/ansible/posix/mount_module.html
