I have bitcoin wallet from 2014. I have saved it encrypted. Since then I haven't checked it, until now. I did sync the whole bitcoin block-chain and when copy my wallet.dat and re-scan wit the client, the wallet got shown as empty. My wallet.dat is 88kb. Bitcon core Client dump of the wallet shows addresses only from 2019 and wallet keys dump from the client returns error. Any help is appreciated.
Did you resolve this issue for yourself? If not, please do the following. First remove save your wallet.dat file into another folder on your pc. Second remove BTC Core entirely from your pc and restart the pc. Finally, reinstall BTC Core onto the pc. Go into the wallet directory, rename new wallet.dat which is created. Place backup wallet.dat file here. Restart BTC Core client and let it rescan the network. This will fix your issue.
