App Crashes

Version gates

iOS 18.2+ needs LiveContainer 3.0.0 or newer (reboot once if problems remain).
iOS 26.4+ needs LiveContainer 3.6.65 or newer.

Specific errors

mremap_encrypted() => -1 - the IPA is not decrypted.
main function with code 0 - IPA format is invalid (SideStore/AltStore would usually reject it too).

Still crashing?

Search GitHub issues for the app name.
Sideload the IPA directly; if it fails outside LiveContainer, the package is bad.
Compatibility gaps for closed-source apps may have no quick fix. Open-source crashes are easier to investigate but still have no guaranteed ETA.

Official sources: Cross-check details on the official documentation and the LiveContainer repository.
