Blocks area did not load properly

[GdNara]

My code previously ran smoothly, but when I reloaded a warning like that appeared, I've tried everything to solve it, but the result still doesn't change. The block that I changed was not saved and changed itself by deleting several parts, which resulted in an error

Hi Gede,

Your project is corrupted. In most cases it is not the fault of the user but of the system. You can try switching to another browser (Firefox is the most recommended browser for App Inventor, next Chrome), but if that doesn't work, people need to run a surgery on your project.

Please upload an AIA copy of your project here, or you can privately send me the project if there's sensitive information inside.

(Canned Reply: ABG- Export & Upload .aia)
Export your .aia file and upload it here.

Or you may follow one or both methods to solve it yourself..

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

@ABG First, import the corrupted project into App Inventor, and then find the corrupted block. In this case, it's the small grey block here. [image] Then, unzip the AIA (on Windows, simply rename it from abc.aia to abc.zip, and then unzip), open the /src/ folder, and go all the way to the file menu.bky. Then, use Ctrl + F, search for these two XML strings: method_name event_name Go through those with the search tool. When I inspect the 42nd event_name, I found this odd block. [ima…

My way of doing it Notepad++ Install xml plugin 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 [bild] Search for in this case for block 4977 (this is where the first issue starts and it might be more) ^(.*?<block ){4977}\K [bild] And as mention above [bild] And you are done.. Edited, Knowing that it is an extension that is missing then we can follow this

That was quick ...

I was about to post my solution, which is that a weird DelayHandler component somehow exists in your project. There are no blocks inside it, so we can remove it and no harm will be done.

    <block id="=Z1amB5m!{|[5;-4X9TF" type="component_event" x="2613" y="351">
        <mutation component_type="DelayHandler" event_name="AfterDelay" instance_name="song_op" is_generic="false" vertical_parameters="true"/>
    </block>
