Export Problems with Admob

Hey guys, I’m not sure how these error messages come about. The thing is, I think it has something to do with the Admob packet. I was so far finished with the game, everything with the export was great and there were no error messages in the console.

When I added Abmob everything worked without errors in the test, after that I couldn’t export and test the game anymore, then these came up Error messages. Does anyone have an idea as to why this could be because I just can’t find a solution?

I’m using Unity: 2021.3.11f1

Thanks in advance for your help!
