Run bitcoin core manually and if it does't help you, follow the suggestion given by goatpig in the post below.
1) Delete the content of this folder:
C:\Users\aorob\AppData\Roaming\Armory\databases
2) Make sure no instance of ArmoryDB is running.
3) Start Armory.
.......is there any way to somehow transfer my unencrypted and imported Armory Wallet into bitcoin core instead? when so how? I dont mind when its technical using Powershell/CLI
You can export your private key and import it into bitcoin core.
For exporting your private key, go to wallet properties and backup your wallet. In the "backup wallet" window, select "See other backup options" and then check "Export Key Lists".
You will see your private key in front of
PrivBase58.
For importing your private key into Bitcoin Core, go to console and enter the following command.
importprivkey <your private key>
As an alternative to Bitcoin core, you can also use
electrum.
In electrum, you can enter your private key and access your fund without any need to download the whole blockchain.
