Exception breadcrumbs

When Unity logs an exception during Play Mode and recording is on, Event Monitor captures the last 20 timeline records as breadcrumbs — context for what happened right before the crash (Sentry-style).

Where to find them

Open Window → Event Monitor and switch to the Exceptions tab. Each entry shows:

• Exception message and stack trace
• Expandable list of preceding Event Monitor records (SUB / UNSUB / INVOKE)

Requirements

• Record must be ON
• Play Mode (exceptions in Edit Mode are not captured by this hook)
• At least one instrumented event should have fired before the exception for useful context

Tips

• Combine with Stack Traces on individual records for deeper handler-origin detail
• Breadcrumbs are capped (20 entries) and reset when you Clear the live bus
