I've had a fairly similar issue recently:
Something related to directly copying a file from inside a zip file on the c: drive to a network samba drive. The file will copy to about 40%, transfer drops to 0 kb/s, the .zip file gets corrupted, and I have to restart Windows to exit the file transfer.
Not 100% repeatable and I'm not sure how many of those specific details are required to trigger it. Extracting the .zip file before copying does seem to prevent it though, which is as far as I've gotten debugging it.
Take pcaps on your client and your server and compare...
I've seen some nasty things happen with broken NICs/drivers. One side gets nonsense data that the peer didn't send, and has poor behavior as a result.
Maybe add iperf3 to the test case to really get the network working...
