Windows doesn't really play well with password-less shares. Always a good idea to at least create a local account on the machine you're sharing from and give that security permissions on the share, using that account's username and password to access the share from other devices. Setting the share permissions for 'everyone' is fine. Anywho, you got one of the windows 11 machines in so there's some progress.
