I cant tell why you are having this issue, i can only say i am using C3 rev2 with UART and C3 rev3 with USB interface and i dont have any problems with flashing them.
Maybe you have to update toolchain/esptool with get.py/get.exe.

It's possible some bug of Arduino esp32 core as it's still OK with esp-idf.

I'm afraid this issue is board dependent and will order some different boards to try and see.

The current board is
