GUI Error: Invalid GUILayout state in FlowchartWindow view. Verify that all layout Begin/End calls match
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

第一个问题可以不用管，这个不影响，这个错误，但是可以正常运行，而且功能没有任何影响，只是控制台不断报错。

如何打印出这问题呢？

用类似于下面这几行代码就行了

string deletePath = Path.Combine(config.ProjectConf.DST, miniGameDir);
Debug.Log($"[Converter] Deleting directory: {deletePath}");
UnityUtil.DelectDir(deletePath);
            

然后根据打印出的日志去删除指定的文件夹。

第二个问题有可能是你之前工程打包的文件和当前Unity工程文件起了冲突，导致你第二个工程没有权限去删除上一个工程的minigame，需要你手动去删除。

删除掉这个，然后再重新打包就行了。 

或者是你重新再另创一个文件夹，导出到新建的文件夹就行了。
