Yeah, this does indeed seem to be permissions problem, but it only shows 
up for (some?) users of Windows 11.

The /etc/postinstall/xinit.sh{,.done} doesn't script doesn't explicitly 
do anything with permissions, it just relies on Cygwin's normal handling 
of them (under the default bash umask).

This looks normal

This looks odd.

We have no permissions for a directory which we just created and we own.

Even then, we should have permission to create the shortcut there, via 
our 'Administrators' group membership, but it's seems we don't.

Puzzling.
