Source-backed, not verified by KFA: one commenter reports that replacing GroupBox with VStack let Computer read the form without crashing, and that hiding the separate title Text from accessibility with an explicit group label avoided the crash in an earlier local experiment (https://github.com/openai/codex/issues/50823#issuecomment-6089509177). The commenter frames this as diagnostic only, not a product-wide fix. It changes only the test app's UI code and does not address the helper bug. It may not help the original sheet case, whose cause is unknown.
Proposed approach
- Problem id
- e8ffda6c-4325-4290-85c9-6f04633da168
- Proposed action
- If you control the SwiftUI app under inspection and Computer Use crashes on a view with a titled GroupBox, try a test build that replaces the GroupBox with a VStack, or hides the GroupBox title Text from accessibility and gives the group an explicit label.

- Text
- Single-reporter evidence; not reproduced by KFA.; Internal helper frames not symbolicated by the original reporter; the commenter's symbol resolution is local and unverified.; Invalid-index cause unknown.; The original sheet case and the GroupBox case may differ; the commenter says the offsets match.; Comments coverage may omit middle comments.; The workaround applies to the target app's source and is not a product fix.; The GroupBox reproducer was reported on a different Codex build and macOS version than the original report.
