Suddenly getting this error trying to open the wallet. Anyone seen this? I excluded the folder from Windows Defender, no luck.

I think your blockhain file is corrupted (first block is bad).![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FUHrbxON.png&t=663&c=Yaiy5WcEdFJ03w)
Try to delete the blockchain files and resync (backup your wallet.dat file always!) .
Did you shutdown your machine while the client is running ?
I probably did. Does anyone know where the blockchain files are saved by default? I have my wallet.dat file.
