Bug: OpenMediaVault SAMBA network share shows `Not a folder - Invalid Password` when not in root folder

### Description

I had open \\192.168.100.2\folder\folder and closed App.

After 4-5 days I opened App and received message I receieved message box: "Invalid password".
I expected windows to enter credentials.

When I manually went to \\192.168.100.2, credential window appeared.

### Steps To Reproduce

1. Connect to Network Share via UNC Path, Navigate to the network path:
\\192.168.100.2\folder\
2. Enter valid credentials when prompted
3. Use the Applicatio.
4. Close the Application and wait for 4–5 days (few restarts) without opening the application.
6. Open the Application. It will remember previouus path.
7. Instead of getting a Windows Credential prompt, you receive a message box: "Invalid password"
8. Manually navigate again in File Explorer to: \\192.168.100.2
9. This time, the Credential prompt appears.
