Cannot open DFU device 2341:0070 found on devnum 13 (LIBUSB_ERROR_NOT_FOUND)
No DFU capable USB device available
Executing command: exit status 74

I'm trying to flash my Arduino Nano ESP32 with code that I've written in the Arduino Cloud IDE.
I'm able to compile and verify the code within the cloud IDE but whenever I attempt to flash the device I get this output error.
Any help would be appreciated.
Thank you

Thanks for a good and detailed bug report. Unfortunately, the LIBUSB_ERROR_NOT_FOUND appearing together with "found on devnum XX" means that the DFU device was available for a short time but then disappeared. It is probably not staying long enough in DFU mode. This is a problem in the device bootloader, or the program (IDE) that puts it into DFU mode. There is not much dfu-util can do about it.
