Hi, I had the same problem with a esp32. Than I just disconect all the cables conected to the I/O pins and I tryied to upload again. It worked!
This is mentioned, for example, in ESP32 datasheet, section 2.4 “Strapping pins”. Note at the end of the section says that GPIO12 needs to have low logic level at startup. Alternatively, if you can not guarantee this, you can permanently set flash voltage to 3.3V, by burning efuses using espefuse.py tool. See https://github.com/espressif/esptool/wiki/espefuse#setting-flash-voltage-vdd_sdio for details. Once EFUSE is written, you don’t need to ensure any specific level of GPIO12 on reset.
