Empty the backpack and restart AppInventor. This should fix the backpack. You will loose whatever blocks you have in the backpack.
Isn't there any other way!? I have VERY important blocks there!!

The Backpack and Copy/paste facilities are in flux after upgrading the Blockly libraries.
(All fluxed up)
I recommend downloading blocks using the Download as PNG right click option, saving the block images to your hard drive by name in a folder.
The png files can be dragged into the Blocks Workspace of this and other Projects.
They also serve as incremental backup.
But how do i do that with the blocs in my backpack? I need to get them back somehow, there are very important
Maybe you can retrieve the original blocks from one of your aia export files you saved?
I don't have them...
Ai2 is an educational tool.
Today you learned a bitter lesson.
So there is no way to get my blocks back from the backpack?... or any way to get the json of them or smth?
Try this
Start a new project (call it backpack if you wish)
Go to the Blocks Editor
Right Click on whitespace
Select Paste all blocks from backpack
Do you get all your backpack blocks ?
Adding blocks to the BackPack does not delete them.
So unless you deleted them from their original Project, they must still exist somewhere.
