It worked!!! Here is what I did thanks for your advice:
Downloaded the aia file.
Changed its extension to “zip”.
Extracted the files and folders in the zip file.
Opened in text editor the files: “\src\io\kodular\ramidagan\MiHuZe\Screen1.scm” and “\youngandroidproject\project.properties”.
Changed the occurrences of the old name “WhatsaPooh” to be the new name “MiHuZe”.
Compressed the files\folder as an aia file.
Imported the edited aia file to Kodular as a new project.
Now I am able to download the apk, install it and the app is running as expected. Thank you all (@dora_paz , @S.Vishwaja , @Boban ) so much for your great help. Its great to know I can keep in mind I am not alone when I have unexplained issues.
