Using server: https://iosbuildservertest.appinventor.mit.edu/ building iOS version (.ipa of for App Store) is working fine, but when building Android version (.apk or .aab), it fails, and I get the following error:
I had the same problem in December 2024 and reported it: https://community.appinventor.mit.edu/t/android-build-on-https-iosbuildservertest-appinventor-mit-edu-server/133528/1
it was fixed at that time, but seems to be back again
Note: Fails with an empty project, size of project is not the issue
