Based on my understanding, you mapped NAS in windows 10 and have no problem to access mapped NAS in File Explorer. But you cannot browse the mapped driver via any application. Is that right? Please feel free to let me know if I have any misunderstanding.
It seems the issue is that you are running some programs with administrative privileges but they cant see drives mapped as a standard user.
Try to configure the EnableLinkedConnections registry value to 1 and then see if works:
1.In Registry Editor, locate and then click the following registry subkey:
2.Right-click Configuration, select New, and then select DWORD (32-bit) Value.
3.Name the new registry entry as EnableLinkedConnections.
4.Double-click the EnableLinkedConnections registry entry.
5.In the Edit DWORD Value dialog box, type 1 in the Value data field, and then select OK.
6.Exit Registry Editor, and then restart the computer.
