Webdab & Windows 11 issues

I am using the community version of Seafile (9.0.9) behind a Traefik reverse proxy for online data storage.

The problem is that with Windows 11, I can no longer save my files directly to the Seafile network drive via WebDAV. I have already upgraded Seafile to version 10.0-latest, but the issue persists.

Could someone please help me? This issue has been bothering me for days.
