Missing Library causes crash on iOS 26.1 on startup

AltStore is crashing immediately after opening on iOS 26.1.

Looks like it’s missing a library necessary for Keychain.

No source files or tests are named. Start by inspecting the iOS build and dependency-embedding configuration for KeychainAccess.framework, then reproduce launch on iOS 26.1. Done means AltStore launches without the dyld missing-library or code-signature failure reported in the crash log.
