Well, the log tells us that my suspicion is right: a problem in
process-send-string:

Don't worry about the Tramp functions in the backtrace; I have simply
hooked tramp-signal-hook-function into *any* error in order to get the
information. The error comes from process-send-string.

No idea what this "Writing to process" "Invalid argument"
means. Obviously, the argument it whines about is a process object,
which looks proper to me. Maybe the process has died, due to buffer
overflow, or whatever?

Could you, pls, rerun the test with Tramp 2.4.3, and tramp-chunksize set
to 1? It will be slow, but I want to see, whether it works.

In parallel, I'll check whether I could find something about the error
message. Neither process-send-string, nor Emacs on MS Windows, is
something I'm familiar with, unfortunately.

Btw, does this error happen always, or only for huge files? Does it also
happen when you run "emacs -Q"?
