I also tried re-indexed the bitcoin core blockchain, and deleted the Armory database folder, but unfortunately the same error occured again at Scanning Transaction History at 59%.
Have you checked your 'Task Manager' for lingering "
armorydb.exe" process in between those tries?
Because it's frequent in Windows11 when "
Let Armory run bitcoind in the background" is ticked.
If there's a zombie process, 'End task' it after closing the GUI before restarting Armory.
Also, some of your "
Armorylog.txt" and Bitcoin Core's "
debug.log" and "
bitcoin.conf" entries should help.
