I can't upload any picture.So I can only put up the link.
I can be sure this is not because of my code.
Could you please share the relevant blocks of code so that we can assist you better?
It works fine when I use an online connection.So I'm sure this has nothing to do with my code.But when I downloaded it to my phone, it looked like this. It crashed.
It should be triggered by the code you can send your code here anyways
you have a problem with the contains block...

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
