FOUND THE ANSWER!!! (at least for Win11 Home 24H2) File sharing is now working!!
To disable the SMB signing requirement in server (inbound to your Windows 11 Canary Insider Enterprise, Pro, or Education edition device), run the following PowerShell command as an elevated administrator:
Set-SmbServerConfiguration -RequireSecuritySignature $false
To access PowerShell as Admin, Press Win + R keys together to open Run.
Type PowerShell in Run and press Ctrl + Shift + Enter keys together to open the PowerShell prompt with administrative privileges.
THANK YOU!
File sharing is NOW working! I tried EVERYTHING else and yours fixed this nonsense!
MS needs to STOP screwing up stuff that was already working!
