Swift application crashes when loading Admob banner

Question

I am trying to implement a Admob Banner in my iOS 15 app but I am running into some issues with that. When I am launching my app it just crashes with the following error:

Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffee35ddff8)

If I remove the call of the banner I get the following error:

2021-11-26 08:01:47.754819+0100 AdMobTest[26286:817324] [Client] Synchronous remote object proxy returned error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated: failed at lookup with error 3 - No such process." UserInfo={NSDebugDescription=The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated: failed at lookup with error 3 - No such process.}

It would be awesome if someone could help with my problem:) Here are is my code: info.plist:

I have been having a similar error when trying to get an Ad SDK working in the simulator. The "The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated: failed at lookup with error 3 - No such process" error goes away when building to device.
