exception `[NSURL isAdtechEvent]: unrecognized selector sent to instance` when removing HockeySDK - ios

Question

I want to replace HockeyApp SDK with App Center SDK. But when I remove the following line of code var manager = BITHockeyManager.SharedHockeyManager; the following unhandled exception occurs on startup: [NSURL isAdtechEvent]: unrecognized selector sent to instance. I have no clue how Adtech is related to HockeySDK. And there is no method or event isAdtechEvent or similar in my code. What can I do to narrow down this error?
