Description

The Telegram Siri Intents extension (IntentsExtension) crashes on iOS 26.6.1 with an EXC_BREAKPOINT / SIGTRAP (Trace/BPT trap: 5) — a Swift runtime trap (fatalError / precondition / force-unwrap).

Environment

• iOS version: 26.6.1 (23G83)
• App version: 12.9.3 (build 34622)
• Device: iPhone 17,3 (iPhone 16 Pro Max)

Crash details

• Process: IntentsExtension (ph.telegra.Telegraph.SiriIntents)
• Exception: EXC_BREAKPOINT, signal SIGTRAP (Trace/BPT trap: 5)
• Faulting thread queue: com.apple.siri.extension
• Crash location: TelegramCoreFramework, offset 320528 (PC == LR == 0x104452410)
• Triggered via: Siri/Spotlight (SpringBoard → chronod)

A sibling thread (also com.apple.siri.extension) shows the same path with more context, revealing the crash is reached through a synchronous dispatch into Postbox:

PostboxFramework        +1674768
TelegramCoreFramework   +320528   ← trap

The _dispatch_sync_f_slow frame just before the trap suggests a thread/queue precondition failure (e.g. accessing Postbox from the wrong queue) or a force-unwrap of nil.

Additional context

The crash report's appleIntelligenceStatus shows Siri language "und" (undefined) while the system language is "sl" — a language mismatch that may be relevant.

Expected Behavior

The Siri Intents extension should not crash when Siri/Spotlight delivers an intent.

Actual Behavior

The extension process crashes with a Swift runtime trap during intent delivery.
