由于重新启动，我不得不关闭graphdb，但现在再次启动后，我得到了一长串错误......

此处出现错误消息，因为它对于 stackoverflow 来说太长了

我现在正在运行存储工具来导出我在那里的几十个图表，但是有没有办法再次恢复和启动 graphdb？它是 8.0.2 版本，我计划尽快升级它...

所有带有如下消息的 GraphDB 错误都表明 Workbench 未能反序列化包含有关当前活动位置、用户、权限、已保存 SPARQL 查询、应用程序状态（如图表）等信息的内部数据库。

重新初始化工作台的元数据重命名或删除目录{$gdb.home.work}。此操作将仅删除所有 Workbench 特定配置并保留所有存储库数据！
