Can't connect Arduino to PC

Hi,

Recently I connected Bluetooth module to my Arduino Uno. I successively uploaded code and it all worked.

But now when I connect it to PC with USB cable, it shows up as Arduino UNO DFU in the Device Manager, and i can't upload new code.

It doesn't accept drivers, and when i manually select drivers from Arduino package, it says that device cannot start (code 10).

How can I fix this and upload new code to Arduino

Thank you

Have you disabled the bluetooth connectivity?

Yes, tried with and without
