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.
There might be something that causes this issue if it is just your OS it might be a compatibility issue.
Can you try to change the compatibility mode to Windows 10 or 7?
To do that right-click the Armory shortcut --> properties --> compatibility then enable "Run this program in compatibility mode" and choose Windows 10 or below.
Also, do this in Bitcoin core then reboot the PC.
