Modded binary immediately closes app?

Hey, here's my typical app modding workflow: Decrypt .ipa using bfdecrypt (only decryption tool that works on Taurine 14.3, as far as i have found) Extract binary from new decrypted .ipa Thin it using lipo (only if it's multi arch binary) Fix permissions to 755/777 Throw it in GHIDRA and start analyzing Manually apply mods/patches to binary using hex editor, and directly replace original one in app's bundle Now, for some reason, this game https://ift.tt/3zXERML immediately closes after modding. Actually, even without modding, after only first two steps, if i replace original binary with decrypted one, it refuses to start. Does anyone have an idea what it could be, it's a random free game, and i don't think it has to do something with some form of anti-piracy..
