A fatal error occurred: Serial data stream stopped: Possible serial noise or corruption.

I'm trying to upload an example code from Arduino to my ESP32 CAM, the Camera webserver example but for now days now i get different errors while trying to fix it. The below error is one of them, does anyone have an idea what this error is ? And incase my ESP32 is damaged How do I test to know for sure ?

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Looks like a corrupted Flash: A fatal error occurred: Serial data stream stopped: Possible serial noise or corruption.

had the same problem and was due to a corrupted flash. Other Boards were doing good with the same IDE and same USB port on PC.

I have the same issue with my PCB.
Check the pin IO2 - it must be floating or connect to ground
