General issue report

We are currently developing a custom PCB based on the ESP32-S3 that integrates the following components:
- OV5640 Camera
- ES8311 Codec IC (for microphone and speaker functionality)
- Servo Port
- I2C Port
- SD Card Port

While all other components are functioning as expected, we are facing a recurring issue with the camera.

Issue Description:
The PCB works fine initially after assembly, but after some time, the camera fails to initialize, showing errors such as:

"Camera initialization error"
"Camera SCCB failed"

Steps Taken:

1. Testing with Custom PCB:
   The camera works immediately after assembly but stops functioning after some time.
   Testing with ESP32-S3 Development Board:

2. We connected the OV5640 camera using an FFC breakout board and the same pins used in the custom PCB. The same initialization errors occur.

Could you please help us identify and resolve the issue? Any insights or suggestions would be greatly appreciated.

Looking forward to your guidance.
