I’m having repeated Guru Meditation Errors and reboots with my ATOMS3R-CAM AI Chatbot Kit (8MB PSRAM) using the official firmware.

My setup:

• Device: ATOMS3R-CAM AI Chatbot Kit (AtomS3R-CAM+Atomic Echo Base)
• Serial monitor: 115200 baud, macOS, arduino-cli
• Firmware: OpenAI Vision For AtomS3R-CAM v1.0 from M5burner

Behavior:

• Boot sequence completes, WiFi connects, camera detected, OpenAI API key and WiFi SSID/Password read from NVS.
• Camera takes a snapshot, sends it to OpenAI, receives a valid chat_response describing the image.
• Immediately after printing the chat_response, the ESP32 crashes (Guru Meditation Error: Core 0 panic'ed (InstrFetchProhibited)) and reboots.
• This process repeats endlessly.

Example OpenAI response lines before crash:

chat_response: The image appears to show a room with a laptop on a table.
Guru Meditation Error: Core  0 panic'ed (InstrFetchProhibited). Exception was unhandled.

Is this a known bug?
Thanks in advance!
