Screen 1 crashing... why?

[nemlawia2014 (apprendre l'arabe)]

Good morning
I hope you are all fine.

I have made an app with on Screen 1 an horizontal scroll arrangement with 24 horizontal arrangement in witch one 6 buttons to click.
Last week i was finishing 18 horizontal arrangement and it worked well. Since i added the 6 last HO my application doesn’t open it crashes directly.
I also added a Screen (I have 6 screen at total) and now the app is finished

Is it really a problem of Screen 1 when it crashes directly or it can be something else ? The 6th screen ?

Can it help to do Screen 1 as a H scrolling and directly put my 144 buttons inside without HO ?

How can i solve it ?

Thank you very much for your help

The problem may be how you switch the screens. It is very important that you close the current screen if you open another screen. Read this:

How to switch screens correctly

I see many issues done by users because they switched screens not correct. This below is now just one of many other solutions: [blocks] If you dont open/close screens correct your app will get possible runtime errors. Possible errors: (example) Unable to add window -- token android.os.BinderProxy@45d459c0 is not valid; is your activity running? Iam sure you don’t want that. Then please do it in the future and switch screens correct. General Tips and Tricks for App Inventor/Makeroid …

I’ve tried several things. The only thing that worked was to delete 20 buttons (maybe a number of button max for one screen ??
