The project doesn't load on the ai companion

When I tried to scan the qr code or write the code in the ai companion to connect and test the project it does't finish loading. In the app inventor, the load of the export of the elements remains at the highest percentage and the load does't complete. I have also done the same with a blank project without elements and only a connection error appears. It is urgent, what do I do?

Are you using Android or iOS ?
Is your companion app up to date, should be 2.62 or 2.62u for Android?
What device and android version are you using to run your companion app?
