Exporting APP from lovable

Hello guys,
as you might see, im not the best coder when using lovable, but i tried.
I tried to create an APP to be released on Play store. Long story short , i created it, exported and wanted to transform it into Android studio to get a file to upload to Android Play account - I failed.

With chatgpt for over 16 hours total, im lost at this point. I cant get the files to work with android studio, i get like " This page cant be shown". So basically the app fails.

With chatgpt going back and forth, trying to find the solution to fix the issue, its a pure headache.

what can i do in this situation? can i export this to Cursor and somehow save the project using the AI there?
As ive understood, the issue with lovable is that they use TanStack Route which causes the issue.

Please guys, i did not know it would make such a mess. I want the app and now im in a position were i dont know were to go.

I think you're overcomplicating it. If the app is working in Lovable, then the project itself is probably fine. I'd post the exact error and screenshots here before moving everything to Cursor. Chances are it's just a setup/config issue that someone has already dealt with.
