I've also had issues running yay with the pacman module. In fact, using yay with sudo is not recommended, so the installation should somehow be separated from the download. I'm not sure if yay has an option to download, then install separately. I know that is a separate issue (https://github.com/Jguer/yay/issues/1026) but it's important to keep this in mind when trying to run yay using ansible.
