I have a Nano ESP32:

However I can upload fine if I select esptool and “upload using programmer”

Is there a way to fix this?

What happens if you double tap the reset button on the board and then try a normal upload ?

The onboard RGB goes a slow green blink, then:

Ok, so some news. This morning, I turned my laptop on, and uploads worked as they do normally from the IDE!

By this afternoon, I was having the same issue again. I restarted my PC, and it’s working normally again!
