Describe the bug

When launching apps within LiveContainer it crashes. And when trying to launch in multitask it says this:
Failed to start app. Child process has unexpectedly crashed

Verify steps

• I downloaded LiveContainer from releases / actions section or LiveContainer's AltStore source.
• I have the latest LiveContainer.
• I installed LiveContainer through AltStore/SideStore/Impactor/iloader/TrollStore or I'm confident that I signed LiveContainer correctly with all required entitlements.

stephendev0 said "LC needs new stubs" upon me asking. I'm not sure what that means but that's probably what is needed.

Device: iPhone 17 Pro Max
OS: iOS 27.0 DB1
SideStore Nightly는 정상적으로 작동, LC+SS Nightly는 SS로 전환 및 앱 작동불가
양쪽 모두 iloader을 이용하여 설치하였음.

SideStore Nightly works normally, LC+SS Nightly switches to SS and the app does not work

Both were installed using iloader.
