The blocks area did not load properly. Changes to the blocks for screen 5475942398296064_menu will not be saved

[Boban]

My way of doing it

Notepad++
Install xml plugin

Edit an application using a Text Editor. Notepad++ (Windows). Winzip. Screen1.bky. Geany in LINUX

This idea has appeared several times in this Community, it is about modifying the .aia file using a Text Editor. Let's see how we can configure the Notepad++ Text Editor (Windows) to modify our application. REMEMBER that it is ALWAYS a good idea to have backup copies of your projects (.aia files) saved on your PC.

7Zip (no need to rename aia to zip etc)

Loading the project in MIT
Check count of blocks for the affected screen
Check count of <block in *.bky file

Search for in this case for block 4977 (this is where the first issue starts and it might be more)

^(.*?<block ){4977}\K

And as mention above

@gordonlu310

It says that there is a FingerprintSensor component (extension) here, but it does not exist in the project. So I went ahead and deleted it, starting from <block type.

And you are done..

Edited,
Knowing that it is an extension that is missing then we can follow this

Seem to have lost most of my work "The blocks area did not load properly"

Did you uninstall an extension prior this happened, if so Install it back Save project Reload http://ai2.appinventor.mit.edu/
