i dont know because i dont have any knowledge about blocks you used in any of your screens
I had same issue 2 days ago. I recreated same screen…then it worked…now it happens again…
i cant help you without your blocks
I will share blocks if issue with blocks…one moderator is said that screen is broken. Then i recreated and worked. Now it also broked
this is the process
and dont use space in screen name
I have used same in my blocks…it opens if created a new screen. But not opening previous screen
how screens are getting Brocked
Thats why posted here…
are you imported screens
No. Created itself
Since it was me who said that and yes screens can be broken by varying causes…
But if you recreated the screen once again and it worked at first and then failing again, then I’m clue less why this is happening…
That’s why stucking on project…i don’t know i can complete this project
The only thing I can advise you is to use logcat to find out more about the runtime error

Check the block in your first screen. Maybe, you are using On Menu Initializing block, instead of On Screen Initializing block. 
No. I used screen initialize block
Please share screen 1 blocks.
I don’t understand why you ask for help and yet you haven’t shared your blocks. Either post your blocks or I will close this topic. Because you obviously don’t want to be helped.

You can just the block of your first screen so that all community members can analyze your blocks and provide a solution.
