Sorry if you fixed this already and I'm repeating information.

I've ran into this a few times. I usually wind up making a registry change. Windows has something called "Linked Connections" - ocassionally this needs to be enabled to see mapped drives in some software like Quickbooks.

As with anything, if you choose to adjust the registry, make sure you run a backup and use caution to not change something accidentally. Microsoft has an article called "Mapped drives are not available from an elevated prompt when UAC is configured to Prompt for credentials". Method 2 is the change that I've used but that's not to say the Method 1 will not work. Microsoft says it applies to Win7 and Win Server 2012, but I've definitely run into it with Win10 and Win 11.
