Failed to re-package resources.

Hey, First i imported https://github.com/unity-plugins/Unity-Admob this admob plugin and it all worked but rewarded video , so the i imported this one https://github.com/googleads/googleads-mobile-unity.And it was just to complicated so i decided to come back to the first one. I entered the same code but when i wanted to build it , i got this error
