Hi @Wan Feng ,
To narrow down this issue, I have a check list for you.
- Make sure the feature “Limited-access user permission lockdown mode” is not activated. You can check it under Site settings > Site collection features under Site Collection Administration
- Make sure the feature “Workflows can use app permissions” is activated. You can check it under Site settings > Manage site features under Site Actions
- Clear SharePoint Designer 2013 cache to have a try. Please take a reference to this article: How to Clear Your SharePoint Designer 2010/2013 Cache.
