The apk file works if I create your aia file using http://ai2.appinventor.mit.edu.
If I use https://ai2-test.appinventor.mit.edu/ to create the file, the error message comes up:
Runtime error:
No static method setFontTypeface(Landroid/widget/TextView;IZZ)V in class Lcom/google/appinventor/components/runtime/util/TextViewUtil; or its super classes (declaration of 'com.google.appinventor.components.runtime.util.TextViewUtil' appears in /data/app/ ...
A test with Companion or USB is not possible for reasons you know (see above)
