I added AcknowList to my project probably in iOS 13, and have never touched it since. But recently I checked the app and it seems that in iOS 15 I get the following exception:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] instantiated view controller with identifier "UIViewController-0H5-Tf-yWq" from storyboard "Main", but didn't get a UITableView.' terminating with uncaught exception of type NSException CoreSimulator 783.5 - Device: iPhone 13 - Runtime: iOS 15.2 (19C51) - DeviceType: iPhone 13

Now the problem is, that since I changed nothing, I have no idea where this error comes from.
