Hangup on "waiting for the barcode" during making .aab

Just Screen1 changed on label and button.

If your ptoject has grown too large to build on ai2.appinventor.mit.edu, try exporting it and build it on code.appinventor.mit.edu

Thanks for the comments.
code page can build .aab
but another error appeared. so I delete one screen on the project to reduce the size of the project.
At this time, the same “waiting for the barcode” hang up again.

Thanks ABG

Can you still open the project after deleting a screen?

If not, that would be the lastopened bug, which can be repaired in an exported aia file.
