Do you login with your Microsoft account?
In theory this shouldn't happen because in that case Cygwin converts the
primary group (set to the user's SID by the OS) to "Users" to avoid
having the same SID for user and group.
Is 1125370 your primary group id? Can you please paste the output of
OTOH, Windows doesn't care if the token's group list contains user SIDs
but, in theory, they should be filtered out by Cygwin. But then again,
there should be no difference between system start and later calls. Hmm.
Can you please paste the output of `id' and
$ /cygdrive/c/Windows/System32/whoami /user /groups /fo list
in your reply?

Sounds like there's something with cygserver going wrong, but I have
not the faintest what that could be.

Stopping the terminal and restarting cygserver is not sufficient?
Also, does this also happen if you don't start cygserver at all?
When the problem occurs, can you provide an strace from id?
$ strace -o id.trace /usr/bin/id
The id.trace file would be interesting here.
