I need help ! I cannot open my project about the aia file

[TIMAI2]

Could be this:

Project corrupted after deleting screen – cannot open project

This sounds like the lastscreenopened bug. Export your affected aia, use this url to avoid opening any projects: https://ai2.appinventor.mit.edu/?autoload=false Open up the aia project with a zip program and then open the projectproperties file in the youngandroidproject folder in a text program like notepad. Change the line lastopened= to lastopened=Screen1 save the file back into the aia project and try again. Alternatively, upload your aia project here and someone can do that for you.
