My app keep crashing when i open the app

No, this problem is also occur when all the screen, components, assets, extensions are deleted and make the app fully blank. It’s the bug in Fenix 1.5.2 update. And the app must be created before the Fenix 1.5.2 update.

I got my problem solved,
For me there had a Switch Component in app without any initial values, I Gave value for switch text off and on and now app works,
So pls check If there is any Radio button or floating action button or switch in your component lisT without any text, if you face this issue

As we know , The component name can only contain number,letters,and underscores and must start with letter, and when we make any mistake in it , normally kodular will give a restriction, but some times it fails to do that, i had a " - " in one of my component name, It also created same problem, (App crashing), so pls check also the name of all of the component if you face this issue
