eFuses and trouble flashing on ESP32 PICO KIT

[wyatttheee]

Hello,

I'm having an issue flashing the ESP32 pico kit after uploading my code to the board. I get the following error:
rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371

I pulled the eFuse data, but I'm not sure which fuse could prevent the board from operating. My hunch is that I used a GPIO in my code that is involved with flashing and accidentally wiped the flash or set an eFuse.

It would just be helpful to know if one of the fuses is blown and the board is completely dead or recoverable.

Thanks for any help.
