On iOS 11.3 and the Android 7.1 emulator, I found the following:

1. Add the Button and TextInput to the screen (do not change any properties)
2. I execute the block below and see the white screen.

![trim](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/1/81a39f52317c26640342d1498272d1954e92d7e0.png)

If you enter a symbol in TextInput and then delete it, then there is no error.
