Selecting a re-run answer in AI Studio corrupts a specific conversation thread, causing the thread to get stuck

I am experiencing a critical bug with a specific conversation thread in the AI Studio environment that causes data corruption and inaccessibility.

**Environment:**

* Platform: Google AI Studio (Sandbox/Public Interface), Gemini Pro 2.5

* OS: macOS

* Browser: Chrome

**Sequence of Events & Behavior:**

1. **Initial Corruption:** The thread first became stuck after a regular rerun attempt.

2. **Temporary Fix (Waiting):** The thread magically “fixed itself” after approximately one week of inactivity.

3. **Second Corruption (Bug Trigger):** The thread instantly became corrupted again after I performed one specific action: selecting an “incomplete answer” version after using the “Rerun” feature.

**Key Issues Observed:**

* **Instability:** The thread toggles between being accessible (rarely) and completely broken.

* **Export Failures:** All attempts to export this specific thread via Google Takeout result in empty files, confirming the export mechanism fails to handle the corrupted data structure.

* **Reproducible Bug:** The corruption can be reliably triggered by interacting with the re-run answer selection feature.

**Actual Result:**

The entire conversation thread is now inaccessible and unusable, even though the data sporadically exists on the server. We cannot retrieve the history.

tldr: re-run attempts tend to get stuck, which causes even first time runs to get stuck too.

I can provide the specific Thread ID privately if needed for investigation.
