我会尝试停止所有主机实例，并确保没有其他任何正在运行，尽管您不需要这样做。

I would try stopping all host instances and make sure nothing else is running although you should not need to do this.

另一种选择是尝试使用ProcessEplorer（https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer）查看锁定dll的内容。

Another option would be to try and use ProcessEplorer (https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer) to see what is locking the dll.
