Hello friends. I am trying to restore access to my bitcoin wallet, or rather, I am trying to restore the private key. I have been struggling with this issue for the third year, access is lost, the computer with the wallet has long been in the trash. I used the wallet itself many times in 2011-2012, when bitcoin was worth nothing, I transferred btc to friends and acquaintances. As a result, about 200 outgoing transactions accumulated. In general, I did not lose hope during all this time and evaluating my outgoing signatures I found that in some windows and channels there is an obvious bias, which is more than enough to build a grid and try to restore the private key. I read the work of Biased Nonce Sense and realized that their approach is completely consistent with mine and they really did restore private keys, but they do not have the published code. I do not understand anything about building a code and turned to gpt chat plus.  In the end, he made me some code on sagemath, but for 3 weeks now I have not been able to launch it, all the time the babai error, this damn gpt has already shaken all my nerves, it changes some parameters in a circle, but the result is the same, the error still does not disappear. In the end, having dropped my hands, I write on this forum, asking for help to help me set up the code so that it works correctly. If someone can help, please write to me in private messages or by mail. Naturally, the help will not be free, in case of successful restoration of access I am ready to transfer 1 btc. Thank you all in advance.
