My project won't open

I went to open my project today and now it won’t open. I had made a backup before I went to sleep (it was working fine last night), but now that won’t open either? (TypeError) : Cannot read property 'Yg' of undefined

If I remember correctly, you are missing an extension or something similar…


There were no errors in the project when I saved it last night, it built successfully and everything, but I will check the AIA to be sure!

This is usually the case, I checked some old post with equivalent error message and it was extension issue…

Btw, what kind of browser do you use

You have saved me @Boban! It was related to this post on the App Inventor community. It was packaging assets incorrectly I assume from below?

All I did was removed the files and folders that did not contain or start with an extension package name and rezipped it as an AIA.

Glad to hear you solved it but which extension was the one that saved the files there, your own ir…

I was trying to use @UsesAssets and obviously it turned out to be a disaster.

But for some reason it didn’t show the issues while editing the project?

Probably because everything is loaded in memory at the time.
