Not connecting the Digi Spark board to the devices

Hello, since I uploaded the blank code on the Digi Spark board with Arduino Android, my board does not connect to any other device, that is, when I connect it to the computer, no driver is added to the device manager, and now on the phone it says with the otg cable and with the arduinodion program. The board is not connected, which means nothing happens when I connect it to the device
But before I uploaded the empty code, it was properly connected to the phone with the otg cable and I can upload it, but now when I connect the board, it does not appear on any device that I can upload the codes to.
I also checked with all the usb inputs of the computer but it didn't work
