Error Domain=NSCocoaErrorDomain Code=4099

My app says it has built successfully but shows the error "No bundle URL Present" with the following in the log:

 [Client] Updating selectors after delegate addition failed with: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service with pid 90 named com.apple.commcenter.coretelephony.xpc was invalidated from this process." UserInfo={NSDebugDescription=The connection to service with pid 90 named com.apple.commcenter.coretelephony.xpc was invalidated from this process.}

Using Xcode 13, and React Native 65.1 on and iOS 15 Iphone 12.

Can anyone help?
