I have the same error with a new UNO R4 Minima. Arduino 2.3.2, Linux Fedora 40.

So far, tried swapping cables, usb port, reboot, reset twice, verified the file 99-arduino-101.rules. The reset-twice operation crashes the linux host. And there are a lot of posts with this same error. Seems not quite ready for prime time, guys.

Very frustrating.

  Thank you
  
  Here at the dfu-util bug tracker we only deal with dfu-util itself,
  not the Arduino IDE. Arduino bundles their own modified version of
  dfu-util.
  
  This is the the problem that dfu-util sees (exit status 74 is just a
  code for this):
  |dfu-util: No DFU capable USB device available|
  So the Arduino IDE hasn't successfully made a DFU device available for
  dfu-util.
