I just compiled a sketch a few minutes ago (MacOS), unplugged the device and made a few changes to my code. Now I have plugged the device back in (same cable, same device, same port) and immediately upon trying to compile I get this message:

cp: /Users/dennis/Library/Arduino15/packages/esp32 ...

I have this same issue, and I don't see that there was a response to the original. Where can I go for help?
