I am probably missing something, but this seems bizarre (to me)
$ id
uid=197608(Marco) gid=197121(NESSUNO) groups=197121(NESSUNO),114(Account

$ newgrp 545 touch prova2
newgrp: group '545' does not exist
$ uname -svr
CYGWIN_NT-10.0-26200 3.6.5-1.x86_64 2025-10-09 17:21 UTC
what I am missing ?

Marco
