No,  I built an actual 64 bit Windows binary and it worked.

It was a while back. So it could possibly be a newly added
issue. Or it could be that my setup and your setup are different.
In particular it would have been somewhere around commit
ff4873cb8c, because that is specifically fixing a bug which
meant that 64-bit Windows builds didn't work, and once that
was fixed they did work. You could see if that commit works
for you, and if it does then bisect.
