Hi! Welcome!
After you have loaded the bootloader firmware onto the SAMD21, you will need to load the main SAMD21 firmware (https://codeberg.org/cool-tech-zone/tangara-samd-fw). This can be done over USB-C. Once you have done this, you can also burn the firmware onto the ESP32 using USB-C.
Unfortunately I have not seen this error before. It could be an issue with your SWD connection. Please double check that your wires are solidly connected!
Once you have flashed the SAMD21 co-processor's firmware, standard ESP32 tools will allow you to flash the ESP32. We do not have a full tutorial on this, but it should not be too complicated. This document may help: https://codeberg.org/cool-tech-zone/tang...UILDING.md
Best of luck with your build! I am happy to help you however I can!
