Issue type	bug
Affected area	Stability & Crashes
Feature category	Primary
Severity	SEV-2 → 1-high

Reasoning: This is a crash reported through Sentry affecting users in Explorer Alpha. Collection enumeration exceptions fall under the Primary category "Stability & Crashes" and represent a core platform stability issue. Since users are experiencing this crash in production, it qualifies as SEV-2 (1-high) — a Primary category feature broken for some users, with the platform still partially functional for others.

Reasoning: This is a collection modification crash (Collection was modified; enumeration operation may not execute), which is a Primary category crash per issue-triage-categories.md. All crashes affecting users qualify as SEV-2 minimum and require a 1-high label. The label is already correctly applied.
