Windows 11 file share problem

I had a Wi-Fi file sharing network with 2 Windows 10 computers, it was slow but it worked. I added a new Windows 11 Laptop to this network ( Private with File Sharing turned on, no Password Required), the Windows 11 computer can send and receive files with the 2 Win 10 computers.

BUT although the new Win 11 computer is seen in Network on File Explorer of the Win 10 computers when I click on its name I get this:

So I can't share files with the new computer using the old Win 10 computers, any suggestion are welcome.
