After iOS 15 has been released my app started crashing. I personally cannot reproduce this crash, however, in Firebase I can see a lot of them. In most cases it happens when you create a UITextView object or activate an existing one and you have an external keyboard connected to your iPad. Does anyone know what could cause this crash?
