1. Did you re-check your new wallet and compared the addresses? (I'm guessing you did. Of course!)
2. Did you try to re-install the wallet and input back with the new private key/mnemonic phrase? Sometimes the application does not update your balance.
3. Have you tried reaching a support? I'm not familiar with Armor Wallet but a support is actually your last option there.
4. Looking at your funds, it doesn't seem to be stolen or anything as long as the BTC address you sent it is the same as shown on your new wallet.
5. Worst case scenario: You downloaded a counterfeit wallet that looks exactly the same. Try rechecking if you have the correct version and right application.
6. You got some virus, malware or something similar that changes BTC address whenever you copy and paste. Hope not!
