Uploaded android version crashes after Play Services sign in but version installed directly from editor works perfectly

So when i upload an android version of my game to the play store for alpha testing the game which I or anyone else subsequently downloads either freezes or crashes after the Google Play Services sign in. This does, however, not happen when i install the game to my phone directly from the Unity Editor.

Has anyone else had this issue before? This is version 5.3.6f1, play services version 0.9.34.

This is the trace when it crashes:
