So... I realized that I was downloading "koreader-kindlehf-v2025.04-5-gbf8adf285_2025-04-12.zip" from
https://build.koreader.rocks/downloa...85_2025-04-12/ instead of downloading "koreader-kindlehf-v2025.04.zip" from the main github, I managed to start koreader after months with this problem, I'm so so happy, if you are having the same problem as I was, I recommend downloading from the original github (I downloaded it from the site because the tutorial I saw sent)
