运行Neo4j Desktop版本1.0.15。尝试启动数据库会导致启动失败：
数据库无法启动：DB [database-f8950fdd-6b5f-4fea-8c9f-e8457ee1da9a]'v3.3.1'退出状态为“KILLED”。检查日志

可能是你的neo4j还在运行。我通过关闭数据库并重新启动它来解决了这个问题。
平台：Windows 10; Neo4j桌面版：1.1.13
打开命令行窗口并转到neo4j数据库的目录。跑
bin\neo4j status
检查数据库的状态。
如果它正在运行，请运行
bin\neo4j stop
关闭你的数据库。然后返回到Neo4j桌面，单击开始按钮，它可能没有症状。
当我克隆我连接的图表时，我遇到了同样的问题并解决了问题。此后，我可以毫无问题地连接到新图表。
