I've tried to sign/notarize/staple my Electron app via electron-builder, using electron-notarize. I tried it as well in cmd line - both times, same result. Code signing runs without a problem. Notarize (I did wait two days first time, now it's couple of minutes) Stapling - failure `Downloaded ticket has been stored at file:///var/folders/.... Could not validate ticket for.... The staple and validate action failed! Error 65. ` I've checked, and the tickets are downloaded to said folder.

I followed the instructions for electron-builder from here: https://kilianvalkhof.com/2019/electron/notarizing-your-electron-application/ I'm sure I made a stupid little mistake, but after hours of arguing with ChatGPT we are going in circles and after clicking on almost every link in Google, I'm kindda lost.
