版本3.3.0
我将CAP包都改到了3.1.2
继承IDistributedEventHandler<>的handler里注入仓储使用会出现异常，具体信息如下
System.ObjectDisposedException: Cannot access a disposed object.

EasyAbp.Abp.EventBus.CAP 3.3.0 版本下，EventHandler里仓储使用异步即会出现报错

Can't help. You can try manage UOW yourself.

If you cannot solve it, try to reproduce it in the latest version (and also share the project for us), and create an new issue with English.
