There is a pretty straightforward installation guide here: https://btcrecover.readthedocs.io/en/latest/INSTALL/. Setting up the tokensfile itself will be the trickiest part, but we can help you to do that. I would suggest you give it a try. Once set up you will be able to check thousands of passwords a second, far more efficient than anything you are trying manually.

Or as bnbstorm says, you can extract the bare minimum information from your wallet.dat file using the instructions here (https://btcrecover.readthedocs.io/en/latest/Extract_Scripts/), and then share that wallet.dat file with someone else who can attempt to crack the password for you without any risk to your coins. I can give it a shot for you if you want.
