There is another tool that you can use to brute-force the wallet passphrase it was developed by Coding Enthusiast.
You can check that tool from his thread below

FinderOuter is great tool/software and more user-friendly. But with lack of GPU support, btcrecover is better choice on most cases.
I don't have computers with GPU so could give it a try. In FinderOuter where should I enter the words I think they are? Is it in "CustomChars"? If yes, do I put Word1Word2Word3 and it will try all the combinations from that?
