最近，我开始遇到MySQL Workbench 8的问题，其中的操作导致它在初始加载后崩溃。初始负载工作正常，我配置了一个连接。然后，我关闭工作台，重新打开，然后尝试连接并崩溃。此时，我也可以将其打开几秒钟（不执行任何操作），它将崩溃。
一些观察结果：
~./mysql被删除（因此也删除了所有连接），即使尝试点击“帮助”或“添加连接”，它仍然会崩溃版本：
我尝试过：
.deb从MySQL站点安装apt安装这是gdb

事实证明，虽然我的问题非常相似，但是一旦我安装MySQL 8，就必须运行sudo mysql_upgrade以确保一切都已升级。之后，重新创建连接后，MySQL Workbench为我工作，并且没有崩溃。
答案 1 :(得分：0)
我不确定这是否是您遇到的相同问题，或者除了运气不佳以外，还有什么其他问题。但是...我删除了~./mysql/workbench/cache/中的所有文件，但仍然无法保持打开状态。然后从connection_id中删除~/.mysql/workbench/sql_history/。
完成此操作后，我就可以加载了。
