Norbert, thanks for looking into this. I should note that I use a Win32 TeXLive 2019 installation, i.e, I am not using the cygwin tex packages.

Here is the requested information (It's not the same machine, but the configurations are the same):

$ perl -e 'print $^O'
cygwin

$ type -a perl
perl is /usr/bin/perl

$ type -a tlmgr.bat
tlmgr.bat is /cygdrive/c/TeX/bin/win32/tlmgr.bat

$ uname -a
CYGWIN_NT-10.0 WD002589 3.0.7(0.338/5/3) 2019-04-30 18:08 x86_64 Cygwin

If you need further information, please ask. I could provide a strace log if required.
