Can’t open the Thunkable app on iPhone XS ios13

I’m surprised no one else has posted this, but since I upgraded to ios13 I can no longer open thunkable. The app appears to open and after 1 second closes right away. I’ve tried reinstalling but no go.
I can’t test my apps anymore:( is this a known bug or is it just me?
