No DFU capable USB device available

Hardware Nano Family Nano ESP32

I am using the Nano ESP32 on a Raspberry Pi4 with Raspian OS and the Arduino IDE 1.8.19 IDE.
I can compile sketches but cannot upload.

An error occurred while uploading the sketch.
dfu-util 0.11-arduino4
dfu-util: Cannot open DFU device 2341:0070 found on devnum 3 (LIBUSB_ERROR_ACCESS)

The only ports I see available in the Arduino IDE are:
Serial Ports
/dev/ttyACM0 (arduino Nano ESP32)
/dev/ttyAMA0

I am using the ESP32 port above.

NOTEL: I have used this nano device on a windows10 system and have no issues

Thank You for your attention.

So, I came to drop one more feedback. I was using platform.io addon from vc extension on ubuntu 22.04. And I faced the same issue error as above. The suggested solution by that user also saved the problem for me.
