Network file sharing not working between Windows 11 & Windows 10

Thank you for the suggestions. I'll look into along with the one about Hello. Some added findings in case anyone reads this and can off any ideas. I was able to add Everyone as a security permission for Desktop drive E and was then able to have Laptop2 map to it. Tried the same for C and F but the Desktop won't allow me to complete adding Everyone to each drives security permissions - ends up with an 'Error Applying Security... Failed to enumerate objects in the container. Access is denied.' And without adding Everyone to drive F on Desktop, I'm not able to map from Laptop2 but mapping from Laptop1 works fine. So another can of worms opened as I really need mapped access to drive F more than C or E. And recalling that I think Desktop may have originally been pre Windows 10, ownership of files and folders might play a role in not being able to apply the security permissions properly. I just don't know which rabbit hole to go down at this point and really just want my new Windows 11 Laptop2 to behave like my Windows 10 Laptop1 has since I got it 2 1/2 years ago.

I'm not sure if you've tried my solution I posted a few responses above yours. It seems to have helped some people.
Not tooting my own horn. Just hoping everyone can have a solution for until MS gets around to fixing this ridiculousness (which will probably be never). They'll probably not fix it so they can get everyone on Win 11.

:(
best of luck!

It's a fundamental flaw in Windows. Windows Hello, the recommended default login process, does not recognise it as a valid login. You must disable Windows Hello and login using your password. Networking then works fine. You could reenable Hello, but I can see no reason why you might want to.
Microsoft needs to mend this FUNDAMENTAL FLAW in Windows as a priority.

I am having similar problems but in trying to map a Win 11 Home laptop to drives on a Win 10 Home desktop. I have a Win 10 Home laptop that has mapped fine to the Desktop for a couple years now. Initially went through the basic steps to no avail. Have now gone down the rabbit hole of recommendations but basically have SMB 1.0 set, services set, Network and Sharing Center settings all set for discovery and file/printer sharing for private and public with private being current but password protection Off in All networks, and of course the shared drives correctly set and using Everyone in share permissions. Was able to get the two laptops to map to each other and of course the Win 10 laptop still maps fine to the Desktop. Just can't get the Win 11 laptop to easily map to the Desktop. Was able to get one drive to map by adding Everyone as a user to the security permissions on one drive but can't get Everyone set for the others because files are in use or otherwise restricted from being modified to allow Everyone. Still trying to figure out that hiccup.

Tried this, sadly it did not work for me. See my next post about latest experience.
