Looking at the snapshots you sent, the transfer is being done via the MTP protocol, which Windows handles most of the details of (very badly), and it looks like it's hanging, possibly due to trying to access the same device in parallel (which MTP often does not handle properly).
For example, there's a thread trying to get metadata about the files at the same time. Avoiding things like that, or opening any files on the device to view them, while copying from it is advisable.
This FAQ also has other suggestions for MTP related issues:
Toggling mtp_enable to the opposite mode is always worth a try, as it changes how the device is accessed (and the share of what Opus itself handles vs Windows, but Windows always does most of it).
With a camera, assuming it has no other mounting options, putting the SD card in a card reader will give better results in almost all cases, as well as being much faster, since it eliminates MTP entirely and lets you access the files via a normal USB drive. I would do that if MTP is the only option, as MTP in my experience is generally neither fast nor reliable, no matter which software is calling it.
