I checked with the API, and I believe the issue is the extra backslash that's been included in the path

You can replace this function in driver.py for delete books

def delete_books(self, paths, end_session=True):
        import json as _json
        def norm(p):
            if not p:
                return ''
            p = p.replace('\\', '/')
            while '//' in p:
                p = p.replace('//', '/')
            if not p.startswith('/'):
                p = '/' + p
            return p

        normalized_paths = set(norm(p) for p in paths)

        self._log(f'[CrossPoint] deleting {len(normalized_paths)} books: {normalized_paths}')
        url = self._http_base() + '/delete'
        # Server expects form field 'paths' containing a JSON array string
        body = urllib.parse.urlencode({'paths': _json.dumps(list(normalized_paths))}).encode('utf-8')
        req = urllib.request.Request(url, data=body, method='POST',
                                    headers={'Content-Type': 'application/x-www-form-urlencoded'})
        try:
            with urllib.request.urlopen(req, timeout=10) as resp:
                self._log(f'[CrossPoint] delete OK: {resp.status}')
        except urllib.error.HTTPError as exc:
            err_body = exc.read().decode('utf-8', 'ignore') if exc.fp else ''
            self._log(f'[CrossPoint] delete error {exc.code}: {err_body}')
            raise ControlError(desc=f'Delete failed: {exc.code} {err_body}')
        except Exception as exc:
            raise ControlError(desc=f'Delete failed: {exc}')
