Hello şafak
Does that Project have the BLE extension?

No ble extension. Only gyroscope control and accelerometer control program. I don’t use any extensions for this program

Hmm. Perhaps an Anti-Virus program is corrupting the file during the course of checking it?

I will assign your Topic to MIT, see what they see server-side.

I checked my virus program. don’t have any changed info. Also yesterday night I tried my program work. I had backup before close my computer. I close my computer and reopen today morning . First job is open app inventor and my program because I want to change something. But I saw error line.
Thanks for interested for my problem. I made new one Now is ok.
I hope nobody was affected by me.

I’m glad you found the answer!

Never worry about asking questions, even if you’re the one to find the answer.

Would it be okay if we look at the program in your account? We did do a release last night and if for some reason it adversely is affecting your ability to load apps I’d like us to make sure that it’s not a new bug in App Inventor.

I am having the same issue. I am receiving the blocks didn’t load completely error message for a project that was working without issue yesterday (Feb 3). Creating new projects by importing .aia files created between a month and several days ago result in the same error message.

I am still experiencing the same issue today - after the announced fix for FirebaseDB and CloudDB.
Anyone have any idea about blocks not loading properly error??

Since this thread was marked resolved, you’re better off creating a new thread with your problem. It may not have the same cause as the original poster.

You can look my program in my account. no problem. if you want you can this. But this are program is on recycle box must be.

Die letzte Veröffentlichung macht massive Probleme, gibt es noch immer keine Lösung? Ich sollte dringend an einem Projekt weiterarbeiten, aber fast alle Blöcke sind verschwunden :-((

This issue was marked resolved. If you’re having major problems with the new release, please create a new post on the forum and describe your problem.

I know that we did find an issue with eGuru’s project, and we are releasing a fix. We need permission to look at your project to see if it is the same issue.

For those still having this issue as of 2020-02-12, please see this post:

Today I loaded my problem program to testing site. Everything OK in this test site.
But I loaded this program to real mit app site again.
This program give block error again. ( Error is : The blocks area did
not load properly. Changes to the blocks for screen
6694392831803392_Screen1 will not be saved. )

You will keep getting that error until we do the next release, which includes the bugfix on ai2-test. We’ll make an announcement went the release goes out so that you know it is okay to use ai2 again.
