Start by reproducing deletion through the WebDAV DELETE endpoint shown in the report and inspect OCA\Circles\Model\ShareWrapper::getCircle() alongside the Nextcloud log. Trace why it returns null during file deletion; done means the file can be deleted without the reported return-type error, with a regression check for this path.
