If you have a project that contains the PlayServicesResolver plugin, using the plugin will sometimes cause the editor to freeze. This manifests in two ways:

- If you have auto-resolution set to ON, the editor will freeze when opening the project
- The editor will also freeze if you attempt to Resolve manually.

Both of these are caused by the PlayServicesResolver plugin itself, not Unity.

Steps to Reproduce:
1. Open the attached project

Result:
After opening the project you are unable to do anything within the editor and the editor needs to be killed with the task manager.

Expected Result:
The project is opened successfully and you can continue working on it

Workaround:
If you find that the editor is freezing on opening the project, you need to do the following to be able to continue working:

1. Delete the Library folder from the project
2. Open the project and turn off Auto-Resolution via Assets > Play Services Resolver
