Exit status 1 does not occur with chmod from coreutils 8.32-1.
A major change in coreutils 9 was to use the f...at() directory relative
functions, so the error may be related to that symlink, unreported due to a
bug (in our/my patches, underlying, or upstream):
EOPNOTSUPP The AT_SYMLINK_NOFOLLOW bit is set in the flag argument, path
names a symbolic link, and the system does not support changing the mode of a
symbolic link.
Appears that it is a known bug and should have been fixed upstream; see the
test release announcement for many chmod fixes and changes including more
options:
https://cygwin.com/pipermail/cygwin-announce/2025-January/012042.html
"...

Bug fixes
- chmod -R no longer exits with error status when encountering symlinks.
All files would be processed correctly, but the exit status was incorrect.
[bug introduced in coreutils-9.0]
..."
If you can, please check again with coreutils test 9.5.
I am working on updating to 9.6, will recheck as part of that, and fix or
report a regression, if an issue.
Problem does no longer occur with 9.5-1 and 9.6-1 test releases.
Thank you very much for testing and reporting.
