Ok no so it actually becomes unresponsive the instant you paste it. Cursor keeps flashing but no touch response, including on keyboard. One time it was able to change inputs but was still ultra slow, other time crashed
must be an infinite loop in the textinput. perhaps at the native layer
I think there was a react-native-paste-input update recently, could that be the culprit? Did you update it?
I am not a React guy, but I once got weird behaviour when I had a textinput field with a validator on it. That started to interact with predictive text. Disabling predictive text solved it. If this has nothing to do with it than ignore my rambling.
