My app was rejected from Google PlayStore because of broken link. I don't really know what to do again, when the screen initialize the app was to ask permission and create folder in the directory where destined works will be download.
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.

That does not look like App inventor? Is that a different builder?
same problem with mit app inventor
Then show your relevant AppInventor blocks
Ask in the community of that builder
It does not really make sense to ask here while you built your project elsewhere
