esp32 / Big Sur

[xboy8001@gmail.com]

Upgraded to Big Sur (my bad) and now can't upload sketch to esp32 board. I have the latest IDE and board. Here is the error I receive. Have been looking for fixes, any help would be appreciated .

Arduino: 1.8.13 (Mac OS X), Board: "DOIT ESP32 DEVKIT V1, 80MHz, 921600, None"
