Rsync is how Cygwin mirrors are maintained, so simple issues would have been 
reported, and checking would report mirror failures.

Please provide some info about your system per https://cygwin.com/problems.html
by running and attaching the output file as a text attachment to your reply:

$ cygcheck -hrsv > cygcheck.log

What edition and release of Win10 are you running? Home/Pro/... and e.g.

$ regtool list -v /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/Software/Microsoft/
CTF\ ()
BuildLab (REG_SZ) = "18362.19h1_release.190318-1202"
BuildLabEx (REG_SZ) = "18362.1.amd64fre.19h1_release.190318-1202"

What is your cygwin release from uname or /proc/version e.g.

$ uname -srvmo
CYGWIN_NT-10.0 3.1.7(0.340/5/3) 2020-08-22 17:48 x86_64 Cygwin
$ head /proc/version
CYGWIN_NT-10.0-18363 version 3.1.7-340.x86_64 (corinna AT calimero) (gcc version
