Maybe error is caused by AsyncProc extension

Taifun billing extension: Error 3300

After reading the documentation at App Inventor Extensions: Billing | Pura Vida Apps you could have found out, that the Initialize method triggers the OwnItemsLoaded event automatically. Further methods should only be called, after Intialization was successful. Therefore do not use that AsyncProc extension, but call the SubscriptionDetails method for example in the OwnItemsLoaded event. Taifun

what about adjusting your project without using that Async procedure extension?
and go to scxreen1 after your proecessing is done…

You can’t change properties of UI objects using async procedure extension, because they are created on UI thread.

Use finish with result block sending vnumber variable as argument and change properties of grind, circular progress and namber in fisnih with result block - it’s executed synchronously.
