Hello,
If your system is Windows 11 24H2 version, I suspect that the problem is caused by SMB signing. We recommend that you open PowerShell as an administrator and run the following command to disable SMB signing and restart your computer to see if the issue can be resolved:
Set-SmbClientConfiguration -RequireSecuritySignature $false
Set-SmbServerConfiguration -RequireSecuritySignature $false
SMB Signing Behavior Control | Microsoft Run
If the problem still cannot be solved, please ask if there is any related error message when you cannot map the shared file. If so, please take a screenshot and reply here.
