I did try the rebuild an rescan, but it still gives the same results. The computer in questions is Windows 11, and it also recently downloaded and installed some upgrades.
As a test I copied the wallet to an older Windows 10 PC I have with Bitcoin Core 25.0, and Armory works as it should from there. It looks like the issue is perhaps Windows 11 related. I'm pressed for time today, but I will plan on sending logs to you tomorrow from the Windows 11 PC.
Thank you for your help.
